need some help understanding the addEmployeeObject method …when does it get it called, the Add button gets clicked, user edits first and last name, selects dept etc…why create an NSSet w/one member and what does the ‘primitiveValue forKey’ return …I’m just not getting it …

ok…went back to chapt 9 and can see that a proxy object for employees is returned then added to…KVC and all that…still don’t quite understand why ???
