OK, I managed to replicate my problem in this example project: http://strangeinversion.com/weird.zip
If you are interested download it, only 44KB. It contains two core data entities: BigBagOfFruit and Fruit. 1. Run the program 2. Add a bag 3. Now add some fruit in it ;) 4. Move your mouse around the window and look at your console: NSManagedObjectContextObjectsDidChangeNotification get called all the time... 5. Go to fruit class, comment out: [self setName:@"Banana"]; 6. Repeat 1 through 4, problem is gone. That's what I noticed in my program, whenever there is ANY SETTER within the draw method that is called from MyView's drawRect, I get this behavior. Any thoughts? Thanks a lot. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
