This message means that the managed object model changed. Rather than lossily loading pieces of the persistent store, Core Data simply refuses to load persistent stores that contain managed objects whose entities are different or nonexistent in the managed object model. You'll need to revert your managed object model, and if you want to continue using your data set you'll need to write a mapping model: http://developer.apple.com/documentation/Cocoa/Conceptual/CoreDataVersioning/Introduction/Introduction.html Hopefully you're following best practices and have a known working managed object model in your version control system. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
