I override: -autosavesInPlace -readFromURL:ofType:error: -writeToURL:ofType:error: -saveDocument: plus some others (like -printDocument) which I don't think are relevant. > > It is indeed -updateChangeCount: that controls the 'Edited' state.

That should > be getting called by the undo mechanism, but it would be good to verify. It's being called only once when the document is loaded. It gets called with NSChangeCleared, which I guess is what you would expect. I've no idea why it isn't called after edits. If I return NO from autosavesInPlace, I see the same behaviour. The dirty dot in the red button does not appear after an edit. If I listen for text did change notifications from the text view and call -updateChangeCount in there, then everything works normally. > > The only other idea I have is that maybe you need to invoke -[NSTextView > breakUndoCoalescing] before saving, like TextEdit does. I added this, but it doesn't seem to change anything. Thanks for your thoughts!
