That's what I tried first, which wasn't working, before I read the docs
further:
"This property is not key-value observing compliant (see Key-Value Observing
Programming Guide)if you are using Cocoa bindings, you cannot bind to the
hasChanges property of a managed object context."
That would have been perfect. Maybe I will submit an enhancement radar to
get this value KVO compliant.
The notification will actually work well for my purposes. That option should
have been obvious but I guess this is my d'oh! du jour.
