The key word there is "its". You're inserting into another context.
Oh well, assuming that I do need to call refresh: on the
NSArrayController, how does one solve this architecturally?
Exactly as you appear to have already done. Register for change
notifications from the second context and update the array controller
on receipt.
Now, if I need to nudge the NSControllers to make them update
themselves, that means that the
model objects need to know about the controllers.
I'm not sure how that follows? The model objects don't need to know
about the controllers -- controllers know about other controllers.
Managed objects themselves don't need to know...
