How to get VO row of the focus node in hGrid

Question

Hello Everyone,
I am developing custom screen with the following layout.
Header: Top Node Details
<Table "contains some details about top-node or node in focus in hGrid">
Header: Organization Hierarchy
<hGrid here>
My requirement is to display some additional details about top node of the hierarchy in <table> above. If user sets focus on a particular node in hGrid , then <table> shall display some details about new top node (which is in focus). This is where trouble starts, how do I get the VO row of the top node in focus?
My initial idea was to capture PPR event = "focus" in submitFormRequest and use method getFocusRoot . Below is part of the code:
OARenderingContext renderingcontext = pageContext.getRenderingContext();
HGridDataProxy dataproxy = hGrid.getProxy().getFocusRoot();
DataObject focus = dataproxy.getFocusRoot(renderingcontext, dataproxy(renderingcontext, (DataObject) ???????));
If this is a right appraoch ? If yes , what should be instead of question marks ?
Thank you ,
Aivars.

OK, we can play this game on and on...
I'll ask for a use case (http://en.wikipedia.org/wiki/Use_case) and you don't give any info we don't already know. After an other 10 posts we probably know what you real problem is and can give you the advice which you could have gotten in the fist place.
So please take some time and describe the problem as if you would ask your mother for help. Tell us how the data model is build and how the VO are related. Is there any input from an user involved? Which information from the other view do you need? How do you get to the doDML method? Is there a button in the ui involved?
