Giving error in sharing tab search if content is not folderish

[idgserpro]

Created a minimal Plone with https://github.com/collective/minimalplone4 and pinned to 4.3.14 (so, plone.app.workflow was 2.1.9). Went to http://localhost:12455/Plone/front-page/@@sharing, entered "Re" in input and then "search". I received the following error:

This doesn't happen in http://localhost:12455/Plone/news/@@sharing: instead, "Reviewers" is shown in the table. This error isn't shown to the user interface since it's an AJAX call. Testing with a folderish type (like collective.nitf) works as well.

We didn't test in Plone 5.

I can confirm this. The error does not appear when js is disabled.

[pbauer]

When a user is already in the table because he has a local role and you change that the error is a little different but basically the same:

Again, without ajax it works.

[idgserpro]

I didn't think about searching in Products.CMFPlone, sorry.

But another question arises... should I always open an issue in Products.CMFPlone instead of specific packages in plone.app.* namespace?

[gforcada]

@idgserpro if you know that is about a specific package you can report it there, as a rule of thumb though, you can always report them to cmfplone
