Aha, I see. Let me make sure I understand.
ownerData is defined in set method. That means it's set as many times as many
rows are in the DG, right? But why can't I talk directly to the dataProvider of
my DG? Or using a private var is the direct way?

ownerdata is a variable that is set to the DG's row data.
ownerData = value as XML;
get's the row data. sorry i should have commented it more

understand about ownerData. Is it a hard coded dataProvider name for DG? I am
working on a generic solution, I can't use hard coded names. Sorry, if I am
misunderstanding your solution.

a Combobox as an itemRenderer for one of columns in a DG. I have managed to

What is an actual design pattern for that?
Thanks much for help.
