I have to disagree with your disagreement. :) I am finding calling executeFetchRequest during awakeFromInsert quite problematic. I'd be interested to know more about how you do it successfully. What are the "certain situations"? In my case, creating a new Foo requires finding existing Bars and setting up relationships between them. It seemed to me that doing this in the model layer was better than doing it in the controller layer, so in Foo's awakeFromInsert I do a fetch to find the Bars. But this results in bizarre problems, like the new Foo appearing twice in a tableview (as Michael reported at the start of this thread). Even if I do the fetch but don't actually use the results it's still problematic. Commenting out the one line that calls executeFetchRequest fixes it. (Yes, this is a reply to a month-old thread...) <http://www.cocoabuilder.com/archive/message/cocoa/2008/4/8/203611> -- ____________________________________________________________ Sean McBride, B.
