Re: [flexcoders] Re: Triggering update refresh for dataGrid

Looking through the source one more time;

Adobe, correct me if I am wrong but the error looks like it is in the updateDisplayList().

I can't even find a hack looking at the code. ;-)

            Thanks Mike.  You've basically come to the same conclusion I have.  I
really appreciate your time in trying to figure this out as well..

If you ever get any other ideas, feel free to let me know.  I'm just
planning to move on for now.. (the customer really won't notice they
they have to add an item twice to see it, right? hehehe)
