Re: How to revert to an unedited document window?
That was the suggestion I needed. Thank you. Here's what I did in the windowControler: [doc removeWindowController:self]; [[self managedObjectContext] rollback]; [doc close]; and then I use my normal routine to reload the document.

How to revert to an unedited document window?
I have a subclassed windowController that has an associated core data managedObject called note, a managedObjectContext and a NSPersistendDocument. Sometimes I need to reset everything back to the last time the doc was saved and make the doc clean (isDocumentEdited == NO) so that when I close it the documentController doesn't ask me if I want to save changes. managedObjectContext rollback does restore everything to the last save but I can't get the document to be unEdited. Using [window setDocumentEdited:NO] or [windowController setDocumentEdited:NO} (which I know I shouldn't call) both don't work. Do I have to reset the persistendDocument somehow? Using [NSPersistentDocument revertToContentsOfURL:(NSURL *)inAbsoluteURLofType:(NSString *)inTypeName error:(NSError**)outError] works except the window closes and opens. If that didn't happen I'd be fine. Thanks___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
