Panther, WO 5.2.2.
I have a many-to-many relationship between entity A and B
(A<<-->C<-->>B)
The join entity C has its own primary key and two foreign keys. The
many-to-many is not flattened.
Here is what I am doing:
1/ remove existing relationships from object a and object b (calling
twice removeObjectFromBothsidesOfRelationshipWithKey on join object c)
2/ delete join object c
3/ save my changes
4/ delete object b
5/ save my changes
Everything works alright.
But If I do:
1/ remove existing relationships from object a and object b (calling
twice removeObjectFromBothsidesOfRelationshipWithKey on join object c)
2/ delete join object c
3/ delete object b
4/ save changes
I receive the following exception:
