@sergei-maertens do I understand it correctly that this field is currently no longer used for writing? I was wonder whether the import code needs to add the name in translations if it doesn't exist. Or can we assume that imports have these translations already?

[sergei-maertens]

indeed - when we added translations we forgot that the 'main' field could also still be written to and that results in writes happening with the currently active locale (so if you have the UI in english, it would write to name_en).

Things didn't break so far because the translations are defined after the name field, so those overwrite the name_en and name_nl fields again, but that was not deliberately and works completely by accident.

You can indeed assume the imports have translations already, and if they don't, well, it's one of the things to mention in the 3.0 release notes and a reason why this was postponed until a major version :)

[stevenbal]

I added a changelog entry for it

[sergei-maertens]

Probably better to mention it in the dedicated docs page: https://github.com/open-formulieren/open-forms/blob/master/docs/installation/upgrade-300.rst
