Attempt to insert null key into a com.webobjects.foundation.NSMutableDictionary

I'm having some problems and the only Info I get is Attempt to insert
null key into a com.webobjects.foundation.NSMutableDictionary.

I have looked at a the other articles/ pages I could find, but I am
still unable to determine why I get this error.


I have a flattened relationship between CollectionDescription and
Content.
I am attempting to remove elements from this relationship by selecting
a Content obj from a list, finding which CollectionDescription it is in
and then using the following

collectionDesc.removeObjectFromBothSidesOfRelationshipWithKey(tempCont,"
collections_content");


This appears to work, but when I call
	aCollection.editingContext().saveChanges();

I get the above error.

I have an editing context to use, and as far as I know both my objects
are != null

I have checked the EOModel, but cant see anything wrong with it.

Any suggestions
