Core Data not firing fault when accessing relationship attribute?

[sinewave]

I am using the model described in this chapter under the Entity Hierarchy vs. Class Hierarchy however i am running into the problem where Core Data is not firing a fault when I access an attribute on a relationship. ie

manager.employee.name

To get the fault to fire i have to use:

[manager valueForKeyPath:@"employee.name]

Any ideas on how to remedy this? I am also a little concerned about what else might not be going on behind the scenes?

I have also gone into a little more details about more data model in this SO post:

Bump, anyone?
