Read the documentation for -[NSObjectController selection]. It's right there in black and white: "A proxy object representing the receiver’s selection. This object is fully key-value coding compliant, but note that it is a proxy and so does not provide the full range of functionality that might be available in the source object." > -[NSManagedObject copyWithZone:]: unrecognized selector sent to instance > 0x1adf50 Typically this happens when you've bound a view to the selectedObjects of a controller and not provided a keypath. Often times views copy their object values, but NSManagedObjectContext does not support NSCopying. Make sure that all your bindings are to keypaths, not just to the objects themselves. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
