Hi Jean Pierre,
I'm starting to see that in my error logs too, but unfortunately I
don't
know why it's happening yet. After that error, the editing context
seems to
get hosed.
I understand what tou mean buy "hosed" now that I have played with the
editing context a bit more: it's unusable!
It's therefore rather difficult to recover from that exception...
Looks like a very nasty EOF bug introduced by 5.2.2 (although I can't
be absolutelly sure about it). There seems to be really weird things
happening with to-many relationships in EOF since 5.2.2.
I am not sure everybody should upgrade their deployment machine to
Panther. I wish I didn't.

Has anyone else experienced this error? Here's our output:

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:
