In Core Data documents, I ignore -[NSDocument isDocumentEdited] and instead use
-[NSManagedObjectContext hasChanges].

"In OS X v10.6 and later, this property is key-value observing compliant."

In earlier Mac OS X versions, -hasChanges also more reliably gave the correct answer, although that might be fixed as of 10.7 or so.
