Weird saveChanges() error

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:

[2003-11-05 21:34:30 CET] <WorkerThread12> java.lang.NullPointerException

at com.webobjects.eocontrol.EOEditingContext.saveChanges(EOEditingContext.j ava:3156)
at DocDisplayGroup.saveChanges(DocDisplayGroup.java:352)


any Ideas?

Thanks.

JP.
