Hi all, mostly my future self.

When I have a relationship setup that has the following settings:
1) Owns Destination
2) Delete Rule of Deny
3) Inverse relationship is Optional (I think this should be impossible if the object is owned)

I get the following error when I try to delete an instance:

java.lang.IllegalStateException: undo: undo manager is in invalid state, undo was called with too many nested undo groups

I don't know if this impacts anything other than Java Client, but I've run into it several times and every time I search on this, I only find my posts.

Would it make sense to have a validation rule in Entity Modeler that the inverse relationship of an "Owns Destination" relationship cannot be optional?

Dave
