Hi all, I have a problem with a CoreData-Document. I normally use NSManagedObjectContext#existingObjectWithID:error: method to get the corresponding object for a given Object-ID. According to the documentation it should return nil if the object cannot be fetched, or does not exist, or cannot be faulted.
But in this particular document it crashes (EXC_BAD_ACCESS) with: #0 0x935e3ed4 in objc_msgSend #1 0x949ff700 in _PFFaultHandlerFulfillFault #2 0x949fe585 in _PFFaultHandlerLookupRow #3 0x94a3bb16 in -[NSFaultHandler fulfillFault:withContext:error:] #4 0x94a3ba45 in -[NSManagedObjectContext existingObjectWithID:error:] If I issue a fetch-request with predicate [NSPredicate predicateWithFormat:@"self == %@", objectID] and the right entity it returns an empty array. I can exchange the existing existingObjectWithID:error: call with a fetch, but the fetch is a lot slower ... I guess the document did sometimes contain an object with this objectID but it is somehow broken. Is there a way to check the integrity of a CoreData-document? (It uses the SQL store, on 10.6.6 if that matters).
