Hi Uli, thank you for your answer. I guess it was a poorly asked question. Sorry for that. I know what the exception means and I know that it is a memory problem (btw - caused by NSOperationQueue). I was wondering 'who' is calling the message isTemporaryID and 'when'. But it is solved now.
The word "Category" has probably a special meaning, however, "ASManagedCategory" not. It is just another class name like MyDocument , MyMessage, MyClass.
