ok, i think i'm picking up what you guys are laying down- the DG dataprovider is an arraycollection that comes straight from a query in my CFC. that query contains the exact same columns as properties in my VO, that is why I thought the conversion should happen fine. Seems what I need is to populate my DG with VO's?? Maybe that is the part I'm missing, how do I go about doing that?
thanks everyone, d.
