Generally, views are bound to controllers and controllers are bound
to model objects. Model objects are generally not bound to each other.
Also, getting a "not KVC-compliant for the "foo" property" exception
when interacting with a managed object is often a symptom that the
managed object does not have an entity set. This can happen if the
managed object was initialized with something other than the
NSManagedObject designated initializer -[NSManagedObject
initWithEntity:insertIntoManagedObjectContext:].
