better do it in Actionscript. Use either the
initialize or the updateComplete events to trigger
your itemrenderer change... also consider that you cnt
set a string as the itemrenderer like what you
'seemingly' do in mxml. you wil have to use a
classfactory to be able to use the class/UIcomponent
you want. Moreover,depending on where and when you set
your itemrenderer, you may have to invoke
invalidateproperties(), invalidatesize(), and/or
updatedisplaylist.
