The change in the virtual field did it. I was using the grid as you

said and the orders object would also automatically update the total,

but would grab the orderline subtotals using getDataSet(), which I

assume has the same update issue as getFieldVal(). It would also make

sense that when I opened my edit forms the bizobj would requery as normal.

Thanks for the help.
