You might try overriding with a call to super and setting a breakpoint or adding a log to make sure it's being called as expected (with NSChangeDone). That should be getting called by the undo mechanism, but it would be good to verify.

Perhaps the NSTextView's NSUndoManager isn't the same as the NSDocument's?
This is supposed to work automatically, but maybe you've done something to prevent this. If its delegate doesn't specify one, the NSTextView searches the responder chain for something that responds to -undoManager. Usually that's the NSWindow. If its delegate doesn't specify one, the window will get its undo manager from [[[self windowController] document] undoManager].
Compare the pointers of [textView undoManager] and [document undoManager]. I suspect they're different.
