Master Detail grid with flash remoting

Question

I've been trying to populate a detail grid based on selection
from master grid I finally got the second grid (detail) to populate
when I selected a record from the first grid(master), unfortunately
I lost the text input fields for the master record that I was
binding to from the Master grid. now I'm just getting the detail
records.
The two grids are populated by 2 different queries that
reside in the same CFC.
I first populate the Master grid (userGrid) then when a row
is selected I pass the selected rows primary key to the function
that calls the detail query in the cfc. This query selects only the
records where the Master primary key = the foreign key in the
detail table.
This is a sample of the code that is in the script tag that
deals with the grid:
var responseHandler:Object = {};
var userGrid:mx.controls.DataGrid = userGrid; (this is the
master grid)
var userIdGrid:mx.controls.DataGrid = userIdGrid; (this is
the detail grid)
responseHandler.onResult = function ( results: Object):Void
{userGrid.dataProvider = results.item;
_root.setMode('add');
mx.managers.CursorManager.removeBusyCursor();
responseHandler.queryUserid_Result = function (results:
Object):Void
{userIdGrid.dataProvider = results.item;
_root.setMode('add');
mx.managers.CursorManager.removeBusyCursor();
On form load calls the getData() that populates the
Mastergrid using the master query in the CFC - this works.
the getData() looks like this:
public function getData():Void
var qArgs:Object {};
<cfoutput>
qArgs.status = '#session.status#';
</cfoutput>
_global.listingService.queryAll(qArgs);
_root.setMode('add');
mx.managers.CursorManager.removeBusyCursor();
The master grid makes the call to populate the second grid
(getUserid() in the onchange event, the PKNO column is the primary
key:
<cfgrid name="userGrid" ........
onchange="userGridChanged();getUserid(userGrid.selectedItem.PKNO)">
The getUserid () looks like this:
public function getUserid(pkno:String):Void
var userArgs:Object {};
<cfoutput>
userArgs.pkno = pkno;
</cfoutput>
_global.listingService.queryUserid(userArgs);
_root.setMode('add');
mx.managers.CursorManager.removeBusyCursor();
This function is populating the detail grid with the correct
data. When I select a row from the master userGrid.
The right hand panel has textinput fields for the master
record that are bound to the master grid- userGrid. Below these
textinput fields I have the detail grid - userIdGrid that can
contain 1 or more rows. I can only get one or the other to
populate, not both.
Is there a problem with the resultHandlers each specifing the
.dataprovider?
Any help would be greatly appreciated.
Thanks in advanced for any help,

You call setMode() a lot, perchance you are clearing the
wrong data there when you don't expect it.
