Crash when binding array controller to Core Data

Reported by Brandon Walkin | August 30th, 2009 @ 01:19 AM

My app's seem to crash when trying to use your framework and core data in the same application.

I often need to use an array controller and once that array controller is bound to an entity, the app will crash unless I remove the toolkit framework.

Here is the data from the console:

The Debugger Debugger is attaching to process [Session started at 2009-08-16 20:38:01 -0400.]

Comment thread from old issue tracker:


I've never used Core Data so I'm not sure why this is happening. Would you be able to investigate this and see if you can narrow it down? Could it be my category on NSApplication?


I would like to but I am a newbie to coding desktop software.

I've narrowed the issue down to when you bind the array controller to the SharedObjectController, which is required for my project. Other than that, it builds and works without a problem.

If I remove the Array Controller or the framework, it works fine. So I've come to the conclusion that the framework doesn't like it when I bind the array controller to the SharedObjectController.
