Mike's precautionary measure is ticking at the top of my mind... so may be for the time being I will just call ec.refreshAllObjects() just to be integral, consistent, simple and more importantly let not annoy EOF by mistake!!!
I will however, keep Anjo's trick in mind and plan for its implementation slowly. Just a thought, I see Anjo's thought and this issue fix should go into wonder and may go into these API's like: updateRowsDescribedByQualifier(EOEditingContext ec, String entityName, EOQualifier qualifier, NSDictionary newValues, boolean shouldUpdateECPostOperation) and similar one for deleteRowsDescribedByQualifier() API. Thanks so much for all your participation. ________________________________ From: "msch...@mdimension.com" <msch...@mdimension.com> To: Anjo Krank <a...@krank.net> Cc: Shravan Kumar.

Good point .. That trick presumed that the update you performed didn't impact a qualified key. forgetObject wouldn't remove from to-many relationships, right? So be careful on that. Long story short -- messing around behind eof's back is a pain.
