BTW, the main thread sent notification (when main thread moc is saved) does not contain the NSRefreshedObjects key. This would probably be a solution to my problem, but mergeChangesFromContextDidSaveNotification: either does not refresh objects (strange) or their is something wrong since objects are definitely refreshed, so why does NSRefreshedObjects key is not in the didSaveNotification ?
