The basic editor or specific editor for cite type depends the configuration in VE for target language wiki. https://en.wikipedia.org/wiki/MediaWiki:Citoid-template-type-map.json

I can see if those conditions are satisfied if language pair info, the article and the wiki were this testing happend is shared. Not all target languages has this citoid configuration.

@santhosh I could not find a lang pair for which ref translation works. Also, I tried translation with the source option (it seems to be the case in Kazam_screencast_00006.mp4 screencast) - the references are still the same.

Some regression issue is here? Translating the first paragraph in en:Victoria Island (Canada) article to es using the source option:

Compare with cx1:

Presently there are Console errors when any reference is clicked:

Uncaught TypeError: Cannot read property 'element' of null
    at VeCeCXTransclusionInlineNode.ve.ce.View.initialize 
    at VeCeCXTransclusionInlineNode.ve.ce.LeafNode.initialize     
    at VeCeCXTransclusionInlineNode.ve.ce.GeneratedContentNode.render     
    at VeCeCXTransclusionInlineNode.ve.ce.MWTransclusionNode.render 
    at VeCeCXTransclusionInlineNode.ve.ce.GeneratedContentNode.doneGenerating

and

Uncaught TypeError: Cannot read property 'emit' of null
   at VeCeCXTransclusionInlineNode.ve.ce.CXTransclusionInlineNode.afterRender 
   at VeCeCXTransclusionInlineNode.ve.ce.GeneratedContentNode.render     
   at VeCeCXTransclusionInlineNode.ve.ce.MWTransclusionNode.render 
   at VeCeCXTransclusionInlineNode.ve.ce.GeneratedContentNode.doneGenerating

Clicking on 'Edit' a reference produce the following error:

Uncaught TypeError: Cannot read property 'getModel' of null
   at VeUiMWReferenceDialog.
   at OO.ui.Process.execute
   at VeUiMWReferenceDialog.OO.ui.Window.teardown

@Pginer-WMF - please review the following results of comparative reference testing
(1) The issues related to references and the Console errors associated with them have been reported across several tickets:

In QA column: T202165: Content translation: Problem with handling references...
T205420: CXServer fails with HTTP 500: "MT processing error: undefined"
T205429: CX2: Uncaught TypeError: Cannot read property 'element' of null at VeCeCXTransclusionInlineNode.ve.ce.View.initialize (ve.ce.View.js?9c8a2:109)
In QA column: T205521: Working with references is broken in CX2

This task - T199512 - can be made a tracking ticket of all the above since it is the first ticket that describes the required functionality

(2) There is a significant difference in a way how cx2 and the production (wmf.24 with v2 enabled) handle the references.
All examples in the table below are from en:Victoria island (Canada) being translated to Catalan with Apertium.

To summarize:

• cx2 does not differentiate between different types of references, but displays them correctly using the source reference.
• wmf.23 differentiates between different types of references, but they are displayed with many omissions
• The Console consistently displays errors

	Web site reference	Edit Website reference	Console errors when click on the ref
cx2-testing			No errors
wmf.23 v2 enabled			Uncaught TypeError: Cannot read property 'emit' of null

	Book reference	Edit book reference	Console errors when click on the ref
cx2-testing			Uncaught TypeError: Cannot read property 'element' of null
wmf.23 v2 enabled			Uncaught TypeError: Cannot read property 'emit' of null

"Cite news" presents even bigger problem in production - if 'Edit' reference is clicked, nothing happens, a page becomes frozen, the Console displays the error: Uncaught TypeError: Cannot read property 'getModel' of null

	Cite news	Edit cite news reference	Console errors when click on the ref
cx2-testing			No errors
wmf.23 v2 enabled		Clicking on 'Edit' does not open the edit box	Uncaught TypeError: Cannot read property 'getModel' of null

Thanks for checking and the detailed report. I moved this back into development since there are cases where editing the references causes errors.

For this task, the focus is to make specific references work in production. For the same support on our testing servers (which would be desirable), we may need a separate ticket once the cause for the difference in behaviour is figured out.

I have tried examples from @Etonkovidova's comment in T199512#4629883. Haven't tried on cx2-testing, only in production. Article en:Victoria island (Canada) was used for website reference and book reference. There are no console errors when clicking on references and appropriate dialogs are shown for editing.

For "Cite news", there is no information which article @Etonkovidova used, so I tried en:Pioneer_Square_pergola. I translated section starting with "The Victorian-style" and tried editing references which are coming from "Cite news" and the editor opens without any console error. In that section, there is one "Cite web" and four "Cite news" templates. That one "Cite web" displays custom label "Lloc web" inside context item and appropriate dialog for editing web references. Those four "Cite news" templates have generic "Referència" label in context item and generic reference editing dialog is opened. Inside that dialog, there is invisible template "Ref-notícia". Opening the dialog to edit that template reveals there are no editable parameters that are shown for that reference (like title, first and last name of the author, etc.), only the option to add new params.

Cite news context item	Cite news editing dialog

@Pginer-WMF with this new information, how do you want to proceed with this ticket? We can create separate ticket for "Cite news" references and send this one back to QA, as @Etonkovidova might want to do further testing.

I checked how the "Ref-notícia" is edited in Visual editor with an article in Catalan Wikipedia which used such template, and it seems that a custom form is also not present there (probably because of the lack of metadata):

So I think there is not much we can do to support better this particular kind of reference template. The situation is more problematic in Content translation because of some existing issues with references that contribute to the problem to go unnoticed (and we may want to fix):

• T206310: CX2: Highlight references with a template that is missing mandatory parameters after being adapted
• T206309: CX2: Don't show reference details when they are not in the reference
