I’m using a NSValueTransformer object to convert my Core Data to-many ordered relationship from a NSOrderedSet to a NSArray so NSArrayController can use it. I just connected a NSButton to the controller’s “add:” action. I get this:
> NSManagedObjects of entity 'Message' do not support -mutableArrayValueForKey: > for the property ‘header' So it seems that the controller skips my converted value and tries to alter the property directly, which it can’t. I thought that the problem was that NSOrderedSet.array returns an array of funny proxies, but manually copying to a NSMutableArray and returning that didn’t work either. So it seems that I have to make custom actions to add objects, and hopefully the controller will see the changes. But I’m wondering if I should go nuclear and create the NSOrderedSetController that Apple should have done years ago. I don’t know how hard this’ll be. It would be a serving-side Binding class. It would inherit from NSObjectController since NSArrayController would have those extra NSArray/NSSet connection methods. Does the Bindings section of the Interface Builder section of Xcode hard-code the Bindings list, or will it create entries for custom Binding-capable classes? If the answer is no customization, then I would have to connect the NSManagedObject instance to the controller in code. — Daryle Walker Mac, Internet, and Video Game Junkie darylew AT mac DOT com _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
