NSArrayController Update Delay

Consider a NSArrayController in entity mode. When a managed object is inserted into the managed object context the controller's arrangedObjects property is not updated immediately.

Calling a controller 'fetch:' immediately after inserting the managed object into the managed object context does not help. The controller's arrangedObjects property is still not updated.

Perhaps there is a KVO change notification delay between the time when the managed object is inserted into the managed object context and the time when the controller finds out about the change.

Does anyone have any insight into what is going or how to force the NSArrayController's arrangedObjects property to update?

Thanks so much.
