whilst i have source for ERXEntityClassDescription so i can setup a
break point there, i'd like to do so further up the stack but as yet
cant find where to get source to do this.
Can anyone help?
For reference (in case anything is obvious) the exception is cause
by adding an object to a relationship (addTo<RelationshipName>) and
then issuing a saveChanges().
The advertID is the property (FK column) in the child which
references the parent (PK).
Thanks

Sounds like you have the FK marked as a class property in the model.
That will cause problems. Exposing the PK won't cause problems,
though is considered naughty by many.
