I have two Entities: Group
and Member
:
Entity name: Group
Relationships:
Member (inverse:Group) (to-many relationship)
Entity name: Member
Relationships:
Group (inverse:Member)
So a Group
can have several members, and the same Member can belong to several Groups, but the Members
don't know which groups they belong to (there is no inverse)
But something strange is happening. If I add a Member to GroupA
, he is added successfully. If I add the same member to GroupB
, he is removed from GroupA
and added to GroupB
. Any ideas why this is happening? Have I set up my model correctly?
Edit: Set up inverse relationship, but this didn't fix the issue.
