NSArrayController display newly inserted objects twice

NSArrayController display newly inserted objects twice Hi guys ! I'm facing a strange problem with an instance of NSArrayController. In my project, I have an entity with an attribute named "name". This attribute have to be unique, so I have a validation process that ensure the uniqueness : - (BOOL)validateName: (id *)valueRef error:(NSError **)outError { // "name" must be unique NSArray * results = nil; NSPredicate * predicate = nil; NSFetchRequest * fetchRequest = nil; predicate = [NSPredicate predicateWithFormat:@"(SELF != %@) AND (name LIKE %@)", self, *valueRef]; fetchRequest = [[[NSFetchRequest alloc] init] autorelease]; [fetchRequest setEntity:[self entity]]; [fetchRequest setPredicate:predicate]; results = [[self managedObjectContext] executeFetchRequest:fetchRequest error:nil]; if ( [results count] > 0 ) { return NO; } return YES; } I've also added the following methods to ensure that any newly inserted object has a unique name by defa! ult : ! - (void)awakeFromInsert { [self setUniqueName]; } - (void)setUniqueName { NSString * defaultName = NSLocalizedStringFromTableInBundle(@"NewCategory", @"Localizable", [NSBundle mainBundle], nil); NSString * uniqueName = defaultName; int index = 0; NSError * error = nil; while ( ![self validateValue:&uniqueName forKey:@"name" error:&error] ) { index++; uniqueName = [defaultName stringByAppendingFormat:@" (%d)", index]; break; } [self setName: uniqueName]; } This works perfectly in most cases...but the most important one : insertion using an NSArrayController. In this case, my managed object is inserted perfectly in the database, with a unique name, but the array controller inserts it twice in its content array ! It seems like the problem is due to this line in my validation method : results = [[self managedObjectContext] executeFetchRequest:fetchRequest error:nil]; If I comment this line, everything works perfectly (but, obviously, the name is not unique). To ill! ustrat! e the problem, I've created a small project that can be do
