Problems on links in tree
Hi there, I like your TreeView. But there are some Problems for me... - when I add just text everything is fine. When I add links   in preview everything is still fine. But when I save the #tree closes right before the first link. Example:

SectionA  Of course when the brackets are closed the following stuff is not included. Anyone knows how to repair this? btw: I use MW 1.11.0, FireFox, MacOS, MAMP Ben


 * Sorry I haven't come across that problem before, is it the latest treeview version? --Nad 07:02, 28 January 2008 (UTC)

I also have the above problem
same problem as above. i'm using latest version of treeview from SVN on MW 1.14. plz help

version 4.0.9
--Tepo 21:18, 20 January 2008 (UTC)

I've installed Treeview4, version 4.0.9 on a MW 1.6.10. The code is properly included, the image paths (in the source of the article page) refer to the right locations (the gif files are all there where the paths refer to) and the JS script is included in the source page as expected. But the tree is rendered literally as if it was a standard wiki article and as if the magic word was never acted upon. The icons do not show up; the treeview table is not being defined. From tracing the Treeview4 source code, my impression is that neither function Tree nor function treeview are invoked. It looks as if nothing happens after function Treeview4 has executed. Any suggestions how to resolve this?
 * The # symbol is not implied in some older versions of mediawiki, so you may need to either remove the # from the wikitext, or set $wgTreeView4Magic to "#tree" instead of just "tree" --Nad 06:54, 28 January 2008 (UTC)
 * Solved! Thanks a lot! --Tepo 20:42, 1 February 2008 (UTC)

Treeview not displayed

 * 1) i create file Treeview4.php
 * 2) insert code in localsettings
 * 3) but, if i insert in Mediawiki:sidebar, menu not displayed. in Mediawiki:sidebar i insert example from docs.
 * If you want the tree to work in sidebar, you have to add the skin hack to allow the sidebar article to render wikitext, see Sidebar for more detail about that. --Nad 06:48, 28 January 2008 (UTC)

Treeview suddenly stopped working in Navbar
Hello... we have a very strange problem... there have been no changes to the MediaWiki version or Treeview version, but all of a sudden, insted of the Navbar displaying normally, it is full of lines like this:

This is on a shared hosting server (asmallorange) - anyone have a clue what might be causing this?
 * I have no idea why that would suddenly change if no changes were made to any of the code or extensions. I'd recommend upgrading to the latest version as treeview 4 is more reliable code than 3.x. --Nad 06:45, 28 January 2008 (UTC)

White block with width 100%
Help please, i integrate treeview in sidebar and edit monobook.css, but all the same i see a white block with width 100%. In ie6 this block down on content.

look:

How delete white block, all resize to necessary size?

PS: I try with width=100% in css - no result.
 * It must be a css problem, try installing firebug into firefox and then right-click and "inspect element" to see what css rules your tree container has had applied to it --Nad 07:27, 8 February 2008 (UTC)

Monobook.css How-to?
Ok, I'm a dummie... so how do I add the Monobook.css stylesheet to our MediaWiki as described so I can change the font size back down to a more reasonable size... which begs the question, why is it so much bigger when going from 3.6 to 4.0.9?

Thanks --
 * Just navigate to your Article MediaWiki:Common.css and there you can change yout css code. Ben --212.184.19.70 07:11, 19 February 2008 (UTC)

MW 1.12+
Any chance this thing is going to work on MW 1.12, PHP 5? Tim Laqua talk 19:55, 28 February 2008 (UTC)
 * Treeview5.x will be made to work with 1.12, we don't have a 1.12 set up to test on yet, what's it doing wrong? --Nad 19:58, 28 February 2008 (UTC)
 * It's all crazy, here's the HTML that results from the parser function example on Organic Design:

&lt;treeview547c711fe2c3f3 id='47c711fe2c3f3' openlevels=4 root='My example tree'&gt;*Node 1 Node 1.1 Node 1.1.1 Node 1.1.1.1    Node 2 </li>Node 3 </li>Node 4 </li>My Pictures The trip to Iceland </li>Mom's birthday </li></ul> </li>Recycle bin&lt;/treeview547c711fe2c3f3&gt; </li></ul> I've got a 1.12 install set up to work with now and have worked out a solution which should get it working on 1.12, it should be ready within the next few days --Nad 10:20, 29 February 2008 (UTC)
 * Can I get a quick hack (or some direction) to get it working in the mean time? Tim Laqua talk 13:19, 29 February 2008 (UTC)
 * As soon as I get it working I'll update the code. The parser has undergone massive changes in 1.12 and I've had to work out a different way to do the main parser function. --Nad 02:20, 1 March 2008 (UTC)
 * 5.1.0 is ready and tested fine on 1.11 and 1.12, it's almost a complete rewrite, so there may be some new problems crop up --Nad 21:10, 2 March 2008 (UTC)

Use cookies?

 * Has anybody added cookie functionality to this extension yet? It would be great if opened/closed trees remained that way from page to page. SeanFromIT 18:36, 2 October 2007 (UTC)
 * I'm back on tree now and working on custom images and persistence --Nad 00:58, 3 October 2007 (UTC)
 * Persistence is now available via cookies in version 5.x.x --Zven 23:01, 10 March 2008 (UTC)

Suggestion - add thumbnailing of images
I use the following (from line 63 of Treeview5.php) to transform down to 18px: $image = Image::newFromTitle($title); if ($image && $image->exists) { $thumb = $image->transform( array( 'width' => 18 ) ); $v = $thumb->getUrl; } else { $wgTreeViewImages[$k]; } Tim Laqua talk 21:46, 3 March 2008 (UTC)

Where to put tree list?
The plugin looks great and I'm anxious to use it. However, the latest documentation appears to be missing something:

>>Usage

>>Tree-views are created by surrounding a normal nested bullet list within the following couple of examples:

That's great, but with all of the supporting files for MediaWiki, which one of the hundreds of files do I put this in? I'm assuming it goes in Monobook.php, but I'm not sure. I've tried putting it in both Monobook.php and LocalSettings.php, both of which give me a parse error when it hits the first bullet:

Parse error: syntax error, unexpected '*'

What am I missing here?

Thanks, Scott
 * I'm not quite sure what you mean? are you asking where you put the bullet list? it's wikitext and you put it in the article where you want the tree to be... or are you referring specifically to how to put a tree in the sidebar? if so see Sidebar... otherwise please explain what you're trying to do and what the problem is more clearly. --Nad 04:35, 4 March 2008 (UTC)

Nad - Thanks, you answered my question. I wanted the tree view to be in the Wiki Side Bar, as well as a nav tree once I get to a particular page. I'll take a look at the side bar info and see if I can make the appropriate change(s).

Strange Error
I am getting a javascript error and I am not sure what it means of how to fix it.

invalid flag after regular expression for (i in tree.icon) tree.icon[i] = '/wdev_wiki/extensions/TreeView/'+tree.icon[i];/data/www/mediawiki/extensions/TreeV... ---^

Any ideas? Thanks, Pete.

I figured this out! At line 166 in 'TREEVIEW5_VERSION','5.1.4, 2008-03-05' there seems to be a typo. Line 166 is: for (i in tree.icon) tree.icon[i] = '{$this->baseUrl}/'+tree.icon[i];{$this->images} But should look like: for (i in tree.icon) tree.icon[i] = '{$this->baseUrl}/'+tree.icon[i];

I hope it was a typo and I have not broken something else but it seems to work great now.

Thanks for all your hard work Nad

Proposed Code Change for TREEVIEW5_VERSION 5.1.4 2008-03-05
This change will make arguments passed to each tree render in that tree rather than the last arguments applying to all the trees on a page.

Change Line 150 from $add = isset($args['root']) ? "tree.add(0,-1,'".$args['root']."');" : ''; to: $adds[$id] = isset($args['root']) ? "tree.add(0,-1,'".$this->args[$id]['root']."');" : '';

Change Link 167 from: $add to: $adds[$id]

Error with Treeview5 & DPL
I am consistently getting

when trying to use DPL in conjunction with Treeview5. This is the code I am trying to use to dynamically create a listing for a Category:

The tree that is being displayed looks like I'd expect, it's just the error that's the issue.

Thoughts on what I'm doing wrong? I'm by no means a DPL expert but that appears to be working OK.

Internet Explorer 7 not rendering tree view
Hello Nad, I have just installed treeview5 (latest version 5.1.7) and it is working fine on firefox but is not rendering in IE7. Indeed, the same happens when I try viewing pages from organicdesign so it's not related to my installation. The IE error log that show up in the bottom left hand corner says: "object doesn't support this property or method". I have tried this from two different computers. --Apap 18:56, 8 March 2008 (UTC)
 * Thanks for letting me know, I'll see if I can figure out what's up with it asap --Nad 06:02, 9 March 2008 (UTC)
 * Found the problem, in IE the JS object identifier names are not allowed to be the same as element id's --Nad 06:22, 9 March 2008 (UTC)
 * Have you uploaded the new Treeview5.php? Even though the link says 5.1.8 the actual php file still says 5.1.7 inside. I tried it but it has not resolved my IE page renderinng (though organicdesign renders correctly now). Thanks! --Apap 16:54, 9 March 2008 (UTC)
 * Doh - sorry no I hadn't uploaded the 5.1.8 changed - done now :-) --Nad 20:14, 9 March 2008 (UTC)

TreeView not rendering at all
Hi, I updated my MW from 1.9.2 to 1.12.0 and was forced to update TreeView from Version 4 to 5.1.9 therefore, too. Then I discovered that the tree wouldn't be rendered anymore at all. The rest of the page is shown without problems, except an error in the browser. I checked that and found that the problem could be caused using windows as server os. The path is built in windows notation.

part of the browser page source code <script type="text/javascript" src="/wiki/skins/common/wikibits.js?116"> <script type="text/javascript" src="C:\Wiki\xampp\htdocs\wiki\extensions\Treeview5\dtree.js"> <script type="text/javascript" src="/wiki/skins/common/ajax.js?116">

The followng line(57) in treeview5.php causes the problem rendering the path in "C:\Wiki\xampp\htdocs\wiki\extensions\Treeview5": $this->baseUrl = preg_replace('|^.+(?=/extensions)|',$wgScriptPath,$this->baseDir);

The used parameter is set: $wgScriptPath = "/wiki";

I changed your code to the following quick hack and it works now: $this->baseUrl = '/wiki/extensions/Treeview5';

It would be nice if you could check that and give me a quick reply how I should proceed. Thanks in advance. --Chrislee 15:06, 22 March 2008 (UTC)
 * Looks like it is the backslashes in windows which are forward slashes on *nix that are not accounted for in the regular expression. The preg replace would need to be something like

$this->baseUrl = preg_replace('|^.+(?=\\extensions)|',$wgScriptPath,$this->baseDir);
 * to work --Zven 21:56, 22 March 2008 (UTC)

what works for me is the following, slash-agnostic line, not verified on *nix though (--Dannyh 22:06, 25 March 2008 (UTC)): $this->baseUrl = preg_replace('|^.+(?=extensions)|',"$wgScriptPath/",$this->baseDir); I have the same problem, but all of the above workarounds produce an "unterminated string literal" error on the page at this line in the rendered html: for (i in tree.icon) tree.icon[i] = 'D:\Web Applications\DevWiki\extensions\TreeView5\'+tree.icon[i]; Any ideas? --Snuck 02:18, 28 March 2008 (UTC)

OK, by fiddling with our $wgScriptPath, and utilising Zven's solution, dTree.js now loads via <script type="text/javascript" src="/extensions\TreeView5/dtree.js"> and the expand/collapse behaviour now works, but none of the images display. I believe the problem is still with this line in the rendered html: for (i in tree.icon) tree.icon[i] = '/extensions\TreeView5/'+tree.icon[i]; The images are in --Snuck 04:52, 28 March 2008 (UTC)

The only way I could get it to work with the images loading was to change line 70 from $wgOut->addScript("<script type=\"$wgJsMimeType\" src=\"{$this->baseUrl}/dtree.js\"> \n"); to $wgOut->addScript("<script type=\"$wgJsMimeType\" src=\"/extensions/TreeView5/dtree.js\"> \n"); i.e., by hard-coding my baseUrl; otherwise, it is output as The rest of TreeView5.php is as per the OrganicDesign site; i.e., without using any of the above workarounds. This makes no sense to me - it appears that  set in line 57 has a different value when it is used in line 70 from when it is used again in line 181, but I can't see anywhere where its value could be changed. I'll keep looking... --Snuck 00:30, 31 March 2008 (UTC)
 * I suggest another approach (which I haven't tested),  is the problem because it contains a windows path with backslashes instead of forward slashes, and on windows they can be either (http://nz2.php.net/manual/en/function.dirname.php). If you convert these to forward slashes before   (approximately line 59) then the path will be constructed like a unix path.

So change the block to Any feedback on whether this works would be useful. --Zven 00:50, 3 April 2008 (UTC)

I had the problem and it's ok now. Thank you very much. --Teriblus 08:27, 14 April 2008 (UTC)
 * This problem should be fixed in version 5.1.10 --Nad 23:01, 14 April 2008 (UTC)

Experienced the same problem, even when using 5.1.10. Images were not loading, pointing to broken URL when loading: http://mydomain:8080/wikiextensionsTreeview5/img/base.gif

Category tree
Hi, Is it possible to mix this extension with the category tree extension ? --Teriblus 08:33, 14 April 2008 (UTC)

No custom icons in 5.1.10
Hi, it seems it's not possible to specify custom icons for single elements in the list. going through the code, it seems that this is not implemented (at least there is no call to method add with a custom icon set). Line 157 would need to be extended to add an icon if needed. will try to investigate this. Jhf2442 21:16, 19 April 2008 (UTC)

Small comment, for a large tree you can't entirely control the space it takes up, in this case it is quite convenient to put it in the toolbox location. From memory you can enclose the tree in a; [your tree parser function syntax] However you don't want the nodenames to be to long or they get clipped... --78.49.107.231 23:24, 17 May 2008 (UTC)

How to hide navigation box: treeview tied to navigation box???
With Mediawiki 1.13, I have tried to hide the navigation box, or at least set it below the navigation tree.

But NavTree display seems to be tied to the navigation box: whether I try to remove the navigation box from monobook.php or monobook.css, NavTree keeps vanishing.

Any idea how to proceed to solve this? Thanks in advance.

Pb: different styles if logged in or not
With Mediawiki 1.13 / Monobook, The style I chose for NavTree only applies after I log in.

Though I have not set up any CSS rule of that kind, only the lines indicated on the extension main page.

Any idea how to proceed to solve this? Thanks in advance.

Not being displayed in Sidebar
Hi. I installed the TreeAndMenu extension and it works on a normal page but when I edit MediaWiki:Sidebar it doesnt show up on the left side. BTW: I did not modify any css (currently no folder icons are displayed but that is not so important) and to test it I switched to monobook skin using preferences in the wiki interface. I use MediaWiki 1.9.3. When I add $wgHooks['MonoBookTemplateToolboxEnd'][] = 'wfNavTree'; function wfNavTree { global $wgUser,$wgTitle,$wgParser; if (is_object($wgParser)) $psr =& $wgParser; else $psr = new Parser; $opt = ParserOptions::newFromUser($wgUser); $nav = new Article(Title::newFromText('NavTree')); $out = $psr->parse($nav->fetchContent(0,false,false),$wgTitle,$opt,true,true); echo '&lt;/ul>&lt;/div>'.$out->getText; return true; } under the include and I edit the page NavTree I get a tree view under the toolbox but I like to edit the navigation box

Can anybody help me?


 * Ok I found out somebody posted that issue before but I didnt know that I have to edit the skin's php code like said in Wikitext in side bar
 * Thanks anyways
 * Just for those who want to have the same like I was looking for (a tree view in navigation): you dont need the function wfNavTree. Only Wikitext in side bar.

Multiple trees failing
Hi Nad A first, thanks very much for your job. To have a good running with this extension i have made a modification in Treeandmenu.php file  because the variable baseurl was not correctly evaluated (i m not a spécialiste but i have seen this in html source code generated). My wiki site is not available because internal factory site (Converteam factory). Please help my because my modification is not standard. More, i have another problem : it is impossible to have several tree on the same page (or/and on sidebar). Finally, is there a solution to place the tree anywhere in the sidbar ? Thanks to reply. CGT 01/06/08
 * What you want is a way to overide the property for the instance of the TreeandMenu class from something you put in the LocalSettings.php without having to hardcode anything into the extension itself, this gives your code independence of any further developments.


 * More than one tree can be added to an article at any time, the code automatically allows this, there is an option id= which if specified makes the trees current state persistent sing cookies, to test this, open up two browser tabs of the same article with a persistent tree on it, modify the state of the tree on one article, then reload the other articles in the other tab --Zven 23:32, 31 May 2008 (UTC)


 * Thanks for your quick answer. Unfortunately, my poor english dont permit me to understand all very well.
 * So at first, is my modification on baseurl valid ? and why the original code dont work in my configuration
 * Second how i use exactly the "id" option because my test dont work (same id for all tree ...)give me an exemple please
 * for the place of the tree on the sidebar i must test again relatively to talk above
 * Thanks verry much CGT 01/06/08

Hi Nad, Zven I confirme that in my configuration, it is impossible to have more than one tree in article. In detail, the render of the first tree is OK but not for the second (no tree). Effectively, the generated HTML code is not correct (only one tree appear. In fact it is more complicated. The behaviour is very courious. The second tree work well until i add an item in the first tree (the second tree disappear!). The same thing with three tree, the add of one item in the first tree disappear the second but not the third. In your opinion, is it a problem with my configuration (or utilization) or a bug in treeandmenu ? Note : your exemple in organicdesign don't use more than one tree. Have a concret exemple with several tree ? Note : my error console indicate and

Please can you help me because the use of treeandmenu is fundamental for me. Claude Gillet 04 june 2008

 * I'm not getting that problem on any of my wiki's, can you give me the html source of the page giving such notices? --Nad 00:47, 12 June 2008 (UTC)

I got the same problem with having no images @ TreeView while menus were working great. The problem was that the string containg image directory was worng ("\" instead of "/"). So open the TreeAndMenu.php and add "$this->baseDir = preg_replace('|\\\|', "/", $this->baseDir);" AFTER the exsisting content: "$this->baseDir = dirname(__FILE__);"

Customizing width and position
Hi. Thanks for your work. Question: Are there parameters like width so I can pass in the template a different width according to the particular tree? This is relevant for example if your tree is on the right part of the page. And same for position? - 22.05.08
 * Give your tree an id parameter and then you can address it specifically in your CSS --Nad 21:14, 22 May 2008 (UTC)

 * Thanks Nad. I still get the same error message though. The tree will only be displayed if I leave the root blank (root=|). Could it be that an EOL or another funny character is in at the end of $args['root']? How does your source code looks (w/o tidy?)? Do you also have a break after the link|plain name and before the string closing? Regards, JdV 08.06.08

 * I've fixed the problem, but have temporarily lost commit access so I can't update the changes on the SVN. If you'd like to add the patch yourself, go to the block of code that has the line $p = clone $parser (just search for clone), and replace that block with this one:


 * Nad, Per.fect. Both cases, with or w/o mediawiki markup, work now. A BIG THANKS!!!. JdV 17.06.08

Remove the root
How can I remove the "root line" and icon completely as in the example on the DPL website?

Long Tree Items
Hi Nad. I have a few trees working now, Thanks. The new one contains long item names which I can't change; FAQ questions. Even after adapting them to a "short" name, they would take maybe two or three 250px lines. Any ideas how I can render them in the tree? Thanks - JdV 18.06.08
 * Sorry I can't see a simple way of allowing multiple lines currently, I've had this problem as well and haven't found a practical solution yet. --Nad 23:16, 18 June 2008 (UTC)
 * Hi; any news on this? I was asked by a friend to help her setting a page with a menu and she has many longer items which we cannot figure out how to shorten them. I tried some tricks to create a new line without the icon image but I was not successful... Many thanks - JdV 06.11.08

??? Please advice how to proceed or where I made a mistake. Thank you.
 * The problem is definitely the "http/localhost", what are your LocalSettings tree config entries? --Nad 21:23, 3 July 2008 (UTC)

I did not know about "LocalSettings tree config entries", I just followed the installation instruction and added the one line info localsettings

actual workaround:

1.) Added into LocalSettings.php (additionally towards the installation described above)

2.) Added into TreeAndMenu.php after the line (app. 65)

thus corrupting your intended regular expression, but actually this leads towards the intended results

 * Yes, just add an id parameter to your tree so that it can be uniquely identified --Nad 06:03, 5 November 2008 (UTC)

I would like to do this too - where does the id parameter go? I tried adding one to the NavTree page and it didn't do anything other than breaking the tree functionality. Do you need 1.08 to do this? We're running 1.07 (but the guy who's working with me will upgrade us to 1.08). Have looked for clear instructions on how to implement persistence to no avail. Thanks!

dynamic drop-down menu
Hi, I integrated the dynamic drop-down menu into the sidebar on the left side, but now I added submenus and of course I can't see them because the sidebar is too small.

Also we have a working example which works in both browsers at OrganicDesign:Extension talk:TreeAndMenu.php which also shows its CSS rules. --Nad 10:39, 18 January 2009 (UTC)

Problems configuring the extension
Hello, i don't know if this is the right place to ask this but i don't know someone else to ask too, I've followed the instructions from here http://www.mediawiki.org/wiki/Extension:Treeview but it still does not work for me, the tree appears like a nested list and this line {{#tree appears just like a static text (i did changed my MediaWiki:Common.css article. Can you help me to configure this? I really need this to work because it is very helpfully to me,

Thank you very much
 * If you're seeing the #tree symbol then it sounds like the extension's not installed, go to your Special:Version page and see if TreeAndMenu is in the list of installed extensions. Also, it would help to know what version of MediaWiki you're running. --nad 08:27, 21 January 2009 (NZDT)

in Special:Version is only this: ''Product 	Version MediaWiki 	1.13.3 PHP 	5.2.6 (apache2handler) MySQL 	5.0.51b-community-nt-log''

but in my LocalSettings.php file i have include("$IP/extensions/TreeAndMenu/TreeAndMenu.php"); (i also tried with include("extensions/TreeAndMenu/TreeAndMenu.php"); ) and no result. I've tried also with MediaWiki version 1.12.0

Thanks for helping me
 * Specifically you need to see if the TreeAndMenu extension show up in that Special:Version page, if its not showing up in there then you haven't done the correct include statement in your LocalSettings.php file. --nad 12:25, 21 January 2009 (NZDT)

Now i can see the TreeAndMenu in the Special:Version but i can't use the tree; i can use the menu but if i edit the main page and enter the lines {{#tree: }} nothing appears (i did edit the articl http://localhost/wiki/index.php/MediaWiki:Common.css), not even a nested list; what can i do?
 * Root1
 * Sub-item
 * Another sub-item
 * Root2

 * what did you "edit" in the MediaWiki:Common.css (Finally, add the CSS stylesheet to your installation by modifying/creating your MediaWiki:Common.css article (note that's an article not a file). Otherwise, your menu will look just like a nested list.) also check out this article on cache issues... --phalseid 04:00, 22 January 2009 (NZDT)

dTree.js path incorrect
Hello,

Tried to get TreeAndMenu in today but found a potential problem with it. The extension tries to include it's javascript and it uses a full path to do so which is incorrect for my server e.g.

<script type="text/javascript" src="/home/blah/web/htdocs/mediawiki/extensions/TreeAndMenu/dtree.js">

it should be just

<script type="text/javascript" src="/mediawiki/extensions/TreeAndMenu/dtree.js">

The error I believe is on line 64 of TreeAndMenu.php

For example. If I have some thing like this:

and I am on page “sub-sub item3” then the tree on the sidebar should expand up to the level of “sub-sub item3” and the rest (from “Another sub-item” onwards) still remains contracted.

Thanks,

Misformatted URL - Menu View
.../\"/index.php?title=Special:RecentChanges\"

how can i solve this problem? i didn´t find the section within TreeandMenu.php which is responsible for the output


 * Problem is already solved
 * before this line $nodes .= "<li class=\"$class\">$item";
 * Insert
 * $item = str_replace("\\","",$item);

Yup, noobie time again
HI after many days of searching, I think this is deff the right menu for me..I installed it works like a dream... but I would like to add the Menu to my sidebar, I would prefer the Menu, and not the Tree. Could someone point me in the right direction to get this implemented. Thanks in advance, --Satire3rd 18:31, 19 February 2009 (UTC)

Nevermind, I figured it out, now I'm having the same problem Ulli 757...The menu doesnt want to show up on Firefox, or Chrome, IE works fine though. --Satire3rd 18:45, 19 February 2009 (UTC)

dTree undefined
Hey, I know, that this problem has been handled many times before^^ But i can't figure out, why the trees don't display on my machine...

OS: Win Server 2003 MW: 1.14.0 PHP: 5.2.8(apache2handler) Tested Browser: IE7 and Firefox (latest Version) Does someone would like to post the steps, how to solve this problem? menu works fine(thanks to all little helpers;)) but tree-space is empty. IE and FF error message: dTree is undefined. they should show up at the main page; not in the sidebar. Tried the solutions from above but they don't work for me...

Thanks in advance!

Notice: Undefined offset: ... line 209
I'm getting an error printed when using the #menu mode. The menu displays fine but the error prints at the top of every page that displays a menu. Notice: Undefined offset: 8 in /var/www/html/extensions/TreeAndMenu/TreeAndMenu.php on line 209 I first tried the 1.14 snapshot then the Development snapshot to no avail. In addition, #tree mode doesn't display anything at all for some reason.


 * UPDATE
 * This issue is only occuring when using DPS for dynamic menu's
 * Code that causes issue:

If no one else has seen this problem then just ignore / delete this post.--Zinthose 22:39, 6 April 2009 (UTC)

Page Size Bloated with TreeAndMenu
TreeAndMenu seems to load each image used in the tree (folder, page, root icons, etc.) from the webserver, each time they are used. I'm not sure if this is just how web pages work, or if the browser thinks each image is unique and needs to be loaded again. In any case, after I added my tree to the sidebar, each page in my wiki was now >1MB in size (1100 images are reported as being loaded to support the tree). All of the collapsed nodes, and their content, are included in that image count.

After suffering poor performance for a while, I installed the simplistic Firefox Extended Statusbar. It simply reports (in Firefox) the time it takes to load a page, the size of the page, and how many images were loaded. To my surprise, all of my MediaWiki articles were loading 1100 images! Also, each article was greater-than 1MB!

Sure enough, loading the official Treeview extension page results in an 863KB page with 825 images.

Is there any way we can get our browsers to only load each unique image, once?

I love this extension, so until this is fixed, I will artificially reduce the size/depth of the tree. Thanks! -Cedarrapidsboy 16:14, 20 April 2009 (UTC)
 * That status bar is counting all images even when they're loaded from local cache because if you do a full refresh you see the real time it takes to load everything. The large load size shown includes 100's of KB of CSS and JS as well as images, but those items are only transferred rarely. --Nad 01:28, 21 April 2009 (UTC)
 * Thanks. I'll have to use a more reliable network monitor to see what is actually passing over the wire.  One good thing that came out of this experiment, we removed a bunch of information from our trees that likely was only clutter.  :)  The bad news...  not a silver bullet for our performance issues. --205.175.225.24 12:27, 21 April 2009 (UTC)
