I have added a field in the Group RCDC in a Tab (grouping) called "Admin" and marked it as Required within the RCDC.
Now, if I were to take an existing group that has a Member Selection of "Criteria-Based" and change it to "Manual" and click "OK" without populating the "required" field in the other tab, I would be re-directed to the field with the note "The required field cannot be empty" as expected. However, if I fill out the field and submit the request, I noticed it doesn't clear the underlying "Filter" attribute and the request fails with "Group validation failed: Static group cannot update membership filter".
I believe this is related to the fact that the Group RCDC has a built-in event handler when the "Member Selection" changes. But doesn't modify the "Filter" attribute unless you go to the "Members" tab? Seems the even handler is ignored or overridden by the event handler that checks for Required fields to be populated?
Anyone else run into this?
