Hi, I upgraded to 10.6 midway through a project and bugs appeared where there was none previously.
I am now seeing the error "Failed to call designated initialiser on NSManagedObject class '' " when I created an object on the MOC or when I fetch an object for editing. Step by step debugging showed that what seems to generate the error is when I display the screen that allows the user to interact with the data and not when I interact with the MOC in any way. This is code that worked just fine under 10.5. Second bug is when I try to add a property to an entity. I tried to add a property of type NSNumber to an entity that inherits from an abstract entity. Both had been created and work perfectly under 10.5. I added the property, synthesized it, added the UI code and bindings. Data communication from the model to the screen works because I can see the default value appear when I load the window. Values are also being passed from the screen to the model because if I do an NSLog(@"%@", model); I can see the correct values. The problem happens when Core Data tries to save the new entity. If I change the default value I always get the error -[NSCFString stringValue]: unrecognized selector sent to instance 0xe909d70. I am not calling stringValue on this property. Any ideas to what might cause this? -- Best regards, Rui Pacheco _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
