Re: NSMutableDictionary crash on PPC

There's nothing odd about it. It's simple memory management rules. The moment you remove the object from the dictionary the dictionary is no longer an owner and since you've not retained it, neither are you. If nobody else is, it's subject to dealloc as soon as the dictionary releases it If it s

Hey there, Cocoa List! I've got a question about background tasking, and I couldn't really answer myself it by searching in the documentation (or even in the internet). I want to make a background task with an application. Firstly, I used the code they gave as a sample, which looks like this: -

Core data: Inverse relationships with subclasses

Hi, I have a bidirectional one to one relationship between two entities like this: Foo <-> Bar, and Foo has a subclass FooSub. All entities are concrete. Sometimes when I set the inverse relationship it's like this aBar.toFoo = aFoo, and this works fine, but when it's linking back to the subcl

Re: Core data: Inverse relationships with subclasses

If your data store is SQLite, I believe the problem is the subclass FooSub. Since FooSub is a subclass of Foo, CoreData combines both Foo and FooSub into a single table whose columns include all properties from Foo AND FooSub. Consequently, when you create a new instance of Foo, columns from Foo

That's actually how I eventually managed to work out that it appeared to be a subclass/subentity thing. It got picked up on validateForInsert when I was doing a Save As, and I checked the objects, and they all seemed fine. But this actually gives me an idea for a bit more testing that I can do -
