First off, reinstate the VBox.  The override the setter data
(value:Object).  There you can either set the cb's dataProvider like cb.dp =
data.someObject

or if you are doing it in MXML, you can bind the dataprovider of the CB to
some expected property of the data property of the VBox.

Doing it via script is a bit tricky, because if your data value doesn't
contain the targeted property it will throw a runtime error.

OK, now I've gotten rid of the VBox, but still do not see how I can set a
different dataProvider to the comboBox, or dynamically set the
selectedIndex.

Again any help is greatly appreciated.
