No, that's not what I meant. I mean without using any ids, names, and etc.
Something like other environments have: parent.
Why can't I after I got a reference to an itemRenderer simply go up on an
object chain to get to DG and then talk to its dataProvider:
itemRenderer.parent.parent.gd.dataProvider
updating it with a new data from an itemRenderer? am I completely off here?

you can talk to anything in your parentApplication by doing
parentApplication.<whatever id name you gave the dataprovider>
the variable parentApplication is a set flex variable that get's all the data
in the main app.

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 = value as XML;
get's the row data. sorry i should have commented it more

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.
