The keypath: ANY personalNames.value.gedcomString CONTAINS "..." is composed of the following keys: GCIndividualEntity has a KVC-compliant collection property called _personalNames_ which is an array of GCPersonalNameAttributes which each have a GCValue property called _value_ which again have an NSString property _gedcomString_ (by the way these are NSObjects, not Core Data). I am not binding to the keypath in my xib, but obtain the predicate via code. The array controller is bound to a property "individuals" on File's Owner (my NSDocument subclass). When I've loaded the file, I set self.individuals = self.context.individuals, causing a table view bound to the array controller to show the objects; this works as expected, as well as a detail-view connected to the controller's selection. I then attempt to set the array controller's predicate and immediately it dies with the mentioned exception.
