Translation from English to German, the en:Template:Multiple image does not find its equivalent de:Vorlage:Mehrere Bilder and pops up with several items to be reassigned.
Topic on Talk:Content translation
Thanks for the feedback, @Hans Haase.
Based on your comments, my understanding is that Content translation does find the equivalent template, but is not able to fill all the parameters for it. For Content translation to know which are the corresponding parameters to copy the information, the parameters in the German template need to either (a) use the same name as the English ones, or (b) include an alias with the English name in templateData.
The German template "Mehrere Bilder" seems to lack templateData. So you may need to add templateData to it ("Edit source" > "Manage templateData") and include in the information for each parameter an alias with the English name.
Please, let me know if this does not work or you need further details.
It was sometimes functional, but did not save the changes. In anohter section, it was impossible to copy the whole template, again. So I decided not to leave the CXT any stay online until filished to prevent losts. The article will be published today as de:Mercon/de:MERCON translating from en:MERCON.
Thanks for the feedback, @Hans Haase.
Currently, template parameters are often not saved. It is unfortunate since this results in efforts for translators and those reviewing the translators later.Feel free to keep track of the ticket and add any other relevant information.
Thanks!
