Thanks Tracey this is what I'd discovered.
I hadn't realised that:
<mx:whatever dataProvider="{arrDataSource}" />
is different to:
function setSomething()
{
myComponent.dataProvider = arrDataSource
}
So I'm assuming that basically the {} in mxml does all the event wiring to
actually Bind the dataProvider whereas just setting the dataProvider in
actionscript just sets it the once.
Thanks,
Dan
