Hi Keary,
thanks for your reply. Yep I implemented all 4, as per the Design ->
Data Model -> Copy to clipboard template, i.e.
- (void)addEmployeesObject:(Employee *)value;
- (void)removeEmployeesObject:(Employee *)value;
- (void)addEmployees:(NSSet *)value;
- (void)removeEmployees:(NSSet *)value;
However if I implement -setEmployees as per Jerry's e-mail (and
seemingly contravening the advice in the Core Data Programming Guide),
then it works like a charm :-/
Thanks for taking the time to help,
Ken

Hi folks,
I'm clearly doing something daft but unable to see the error of my
ways.
Distilling my problem down into the Department & Employees example,
both are custom NSManagedObject subclasses, each with an inverse to-
many / to-one relationship as you'd expect. My problem is that
Department's custom -awakeFromInsert gets called, yet its -
addEmployeesObject and -addEmployees methods don't ever get called.
If I add employees in the app, it all works swimmingly, but my
custom accessors aren't ever used.
Do you implement both the add<key> *and* remove<key>? The framework
might require both to assume compliance.
HTH,
