Thank you Katkov.. Thank you for developing this input method. :)
Okay, I tried adding &debug=true to the URL but nothing happens. Could it be that this error only shows when I click on the "Preview" button when I am Editing the Form and not in the actual URL? For instance, when I add &debug=true directly to the form url like www.url.com/wiki/index.php/Form:xyzForm&debug=true, then it shows the "There is currently no text in this page. You can search for this page title in other pages, search the related logs, or edit this page" message since its trying to create a new page. When I click on Edit Form, and then click preview, that is the time the error shows. So when I try adding &debug=true to the URL that shows when viewing the preview like this: wiki/index.php?title=Form:xyzForm&action=submit&debug=true or wiki/index.php?title=Form:xyzForm&debug=true&action=submit, then it just shows the form edit page without any previews or errors. So sorry couldnt be of help there since I couldnt get the full error message with problematic line numbers. Are you maybe able to reproduce this by trying to edit the form that has the 2 listboxes and then click on Preview button? The error message shows in 2 pop-up boxes when the preview form page is loaded:
Dialog 1 says: "ext.semanticforms.main: TypeError: jQuery(...).data(...) is undefined" with OK button,
Dialog 2 says: "ext.semanticforms.main: TypeError: jQuery(...).data(...) is undefined" along with a checkbox in the next line that says "Prevent this page from creating additional dialogs" and then the OK button.
But like I said before, although these errors shows when I preview the form edit page (note it happens only when I edit the actual form and not the article that was created based on the form), the form actually works when creating an article using it. So not sure what could be the cause...
And, any suggestions on how I can style these listboxes like I mentioned in (2) above? Are the listboxes showing close to each other because of the other error or is this how its supposed to be? Do you have a working example by any chance?
Cheers!
