MOC NSDeletedObjectsKey notifications on undo/redo show default object values?

Subject: MOC NSDeletedObjectsKey notifications on undo/redo show default object values?
From: George Orthwein <email@hidden>

So I'm nicely using NSManagedObjectContextObjectsDidChangeNotification to track changes to my managed objects. The problem occurs when I insert an object and then undo it (or delete an object and undo/redo). The deleted object notifications show all the object attributes at their initial default values. Specifically, I'm setting a uuid string attribute in awakeFromInsert that unfortunately displays as nil in the delete notifications generated from the undo/redo.

I can probably work around this somehow but I'm wondering if there is a known solution.

(Or maybe I missed a way to set dynamic default values via the data modeler? :)

Thanks,
George
