In this narrowed down code of the bug it will log this on removeObserver (please ignore the Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason) because I just created simple main sample code to narrow it down: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cannot remove an observer <Observer 0x10ac00> for the key path "targetPhoto.name" from <NSMyArrayController 0x1099d0>, most likely because the value for the key "targetPhoto" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the NSMyArrayController class.' Also in the debugger setting a breakpoint before the removeObserver po [myTestArrayController observationInfo] You will get: <NSKeyValueObservationInfo 0x10c380> ( <NSKeyValueObservance 0x10da70: Observer: 0x10ac00, Key path: targetPhoto.name, Options: <New: YES, Old: NO, Prior: NO> Context: 0x21, Property: 0x10bce0> ) and doing a further investigation on the observation info: po 0x10bce0 <NSKeyValueNestedProperty: Container class: NSMyArrayController, Relationship property: <NSKeyValueUnnestedProperty: Container class: NSMyArrayController, Key: targetPhoto, isa for autonotifying: NSKVONotifying_NSMyArrayController, Key paths of directly and indirectly affecting properties: none>, Key path from related object: name> Also the sample code I posted will work fine, in case you replace the NSArrayController with NSObject. But it will fail in case it is NSController, NSObjectController. cheers, marc _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
