If you are using a vBox as the container for the comboBox, you could have a
bindable public property var selectedIndex:int and tehn have the internal
comboBox's selectedIndex bound to that (in mxml of course, via actionscript,
you would need setters to set teh cb.selectedIndex)
then inside that cf.properties = {selectedIndex:#}

I've made major progress
I can now dynamically change the dataProvider for my comboBox
itemRenderer. Now I just need to figure out how to change the selected
index for individual rows.
I am open to suggestions!
