Ah, okay. There shouldn't be any need to call -processPendingChanges
there, unless you're programmatically working with your own undo
groups.
What I am seeing is that my code changes a managed object property,
I undo, and no change occurs in the managed object. The property
affected is a binary attribute (a CATransform3D as bytes).
Does your code changing the property trigger a KVO event (i.e. are
you missing a call to -willChangeValueForKey:) ? Do you see
notifications from the MOC when you initially make the change ?
Are you undoing programmatically or as a user ?
The undo behaves the same as before I added any notification
processing however.
That suggests the problem lies elsewhere.
