[SOLVED] Re: death in dealloc

Spot on, Steven. My memory management was faulty. My object had been instantiating another object via alloc that it kept a reference to in an iVar, and my (outer) object released that instantiated (inner) object in its -dealloc method. I refactored the code, and changed the way I acquire the (in

That particular function is trying to CFRetain the result of -identifier on your store. If you've overridden it, make sure it never returns nil and it always returns the same UUID at least until someone calls -setIdentifier. The UUID should also be set in the store's metadata with the key NSSto
