Wonderful reply Tracy. Thanks. Bubbling the event, that's the perfect tip.
As for not being able to walk the items in the list, that seems
counter intuitive to me, but okay. As long as I know the behavior I
can find a way and stop pulling my hair out wondering why I can't do
what Flex doesn't do in the first place.
Thanks a ton for the clear and very helpful reply.
