core data + undo + to-many relationship

Hi everyone In a core-data model I have a 'layer' which contains a to-many relationship to a set of 'effects'. When I add an effect, everything is working well. When I use Ctrl-Z to have the undo manager undo the addition of the effect, then none of my custom accessors are fired (so my G

OK, I can understand that its more efficient - and have now seen my error (I think). The listener to the remove event is getting fired (via KVO), but all of the data on the core-data Effect instances is nil, so my code discards the event. I've got my own uniqueID value set up on the Effe

Actually, extra note here... Things would probably work OK in my code if the object's values hadn't been set to nil by the time I get a willTurnIntoFault message. Is there a way to be notified prior to the event taking place? Thanks -- John Clayton Skype: johncclayton On 7/12/2008, at

core data + undo + accessors

Hi all, Tell me if I'm missing the point please. With core data and undo, apparently the undo system + core data (not sure if its a combination of them both), do NOT fire accessor methods on core-data objects when the undo manager changes the state of the object model. For example (outli

Core Data is specifically designed not to invoke accessor methods when undoing or redoing changes. For efficiency, it just rolls back the state of the objects. It does NOT perform the reverse of your original actions. Of course, during an undo/redo, KVO notifications are fired, so your UI s

I'm a bit confused by your post. NSPredicateEditor doesn't compare any dates, it just creates NSPredicates. Maybe you're saying that if you have a NSDatePicker in your NSPredicateEditor, that it creates a predicate with a date set to 13:41:40. If that's the case, then it probably has more to do
