It is actually - especially because you can unit test it without the ui
I'm using a model class for all my comboboxes, which contains the
dataProvider and a selectedIndex property.
However, if you don't want to go down that route, you can either use a
binding function,
if the whole dataProvider is replaced you add CollectionChange
handling to your dataProvider
if it is changed. You can use myArrayCollection.itemUpdated(..) to
trigger this event.
Cheers
Ralf.
