title: NSFetchRequest setReturnsObjectsAsFaults: doesn't work
body: <p>I'm working on an application based on Core Data.  I'm doing a fetch on <code>Item</code>. I don't want the fetched objects to be fault when returned because I'm sure they will be accessed immediately.  Thus, I set the <code>returnsObjectsAsFaults</code> to be <code>NO</code>. However, it doesn't work for me.</p>
  
  <p>Below is how I set up my <code>NSFetchedResultsController</code>.</p>
  
  <pre><code>NSString *cacheName = @"cache";
  [NSFetchedResultsController deleteCacheWithName:cacheName];
  
  NSManagedObjectContext *context = APPDELEGATE.managedObjectContext;
  
  NSFetchRequest *request = [[NSFetchRequest alloc] init];
  NSEntityDescription *entity = [NSEntityDescription entityForName:@"Item" inManagedObjectContext:context];
  [request setEntity:entity];
  NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"dateCreated" ascending:YES];
  [request setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];
  [request setFetchBatchSize:20];
  [request setReturnsObjectsAsFaults:NO];
  
  NSFetchedResultsController *frc = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:cacheName];
  [request release];
  
  NSError *error = nil;
  BOOL result = [frc performFetch:&amp;error];
  if(!result){
      NSLog(@"Unresolved core data error");
  }
  </code></pre>
  
  <p>Any ideas?</p>
  
  <p>Update: Actually, all the fetched objects are  faults.</p>
