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
