[flexcoders] ComboBox question...

[[p e r c e p t i c o n]]

Hi Experts,
I'm trying to do 2 things...one...i'd like theinitial item of my combobox to
be empty...meaning not one of the selectable items, and secondly if this is
not possible...i'd like to be able to handle a click on an already selected
item...it seems that if it's the first one in the list and you click on it
the event doesn't get dispatched...
thanks
percy
