I checked the "Include empty text in choices" checkbox for combo boxes managing relationship attributes so they could be unselected. The option "undefined" shows up in the list and can be selected.
But when I save, the system doesn't save the change. If I select a different related record , it does actually save that change, so this is only an issue for setting the attribute to undefined.
The attributes are not required (and I would just expect to receive an error message if they were). I have no rules that pertain to these attributes. There is no indication in the log of a rollback. This happens whether I use filters or not.
This is all happening in test and I assume the same is true for production. Is anyone else experiencing this issue? I'm using build 2341.
BTW, is there a known-issue/bug list I can refer to? It would be a very helpful reference and save me a lot of headaches.
