Well, this was an idea I had already. Because the old (working) app did just have an array controller, but the new app (the one throwing exceptions) had another array controller bound to the selection of the first one. So I did [ secondArrayController unbind: @"contentSet" ] - but no success. Then I removed the secondArrayController from the nib - no success either. Now, after reading your mail, I deleted the first array controller, dragged a new one into the nib - and everything works! Obviously the old firstArrayController had some memory of having its content bound to by some other controller; a memory persisting regardless of this binding having been unbound, or the binder having disappeared. I am not qualified to call this a bug. But it has cost me more than a day of pointless struggle. Is this persistent memory of NSArrayControllers somewhere documented? And is there a way (programmatically) to clear this unwanted memory? Thanks for your help!
