Add this code to your NSDocument subclass:

- (BOOL)validateUserInterfaceItem: (id <NSValidatedUserInterfaceItem>)
anItem {
   SEL action;
   
   action = [anItem action];
   if (action == @selector(revertDocumentToSaved:))
       return [self isDocumentEdited];
   else
       return [super validateUserInterfaceItem: anItem];
}
