Re: [flexcoders] Re: Binding scroll position to the selected index
I don't see a selectedItemChanged event ... I only see a change event, and that only gets fired when a user manually clicks and changes an item.

Re: [flexcoders] Re: Binding scroll position to the selected index
So, I got both the valueCommit and the Observe / tag to work when
manually setting list.selectedIndex, but not the list.selectedItem property.
You can check out either version ... For those without the Observe /
tag, just remove those two ... They appear to be functionally equivalent
in this case.

Tracy,
Thanks for the valueCommit suggestion. You shed a new light on that
event: a lot less code your way. :)
