PowershellGrid Widget questions in Dashboards

Question

Question about SelectedRows / $globalselecteditems for Powershellgridwidget
I have a dashboard which has 4 grids.
1. The top grid shows the health of our servers
    This grid is based on a Visualization!Microsoft.SystemCenter.Visualization.StateWidget
2. The second grid displays the relevant databases for the server/s chosen in the top grid - note more than 1 row can be chosen
    This grid is a powershellgrid widget 
3. The third grid shows custom alarms for the database/s chosen in the second grid
    This grid is also a powershellgrid widget
4. At the bottom, we have a generic details pane which at the moment only displays the details for the top grid which is Server Health.
   This grid is a Microsoft.SystemCenter.Visualization.GenericDetailsWidget 
My questions are:
1. Given that the powershellgrid widgets use $globalSelectedItems to pass context between widgets, how do you stop the second grid from deleting all rows if you chose a row in the third grid.  It works fine if you have chosen an item from the first grid,
then the second and so on - chosing an item in the third grid will blank out my second grid
This is what I have tried - In my third grid which displays alarms, I have prefixed the "id" of the dataobject to include a nominal identifier so that I know  what widget has sent the "id" with something like this.   
           $dataObject["Id"] = "Alarms" + $($i).ToString("00000") 
So in my second grid I thought I'd be able to exit without losing the contents of the grid with something like the following.
========
Param($globalSelectedItems)
#Test what the item is so we don't lose our rows if item not related
# exit if it is not related
$anItem= $globalSelectedItems | Select -First 1
if ($anItem["Id"].Contains("Alarms"))
 exit 
=====
2. How do you pass a "SelectedRow/s" to a Generic Details widget from a Powershellgrid widget?  Has anybody done this yet?  I would like to display the selected row from whichever grid has focus.  Also, unlike the Datagrid, the Powershellgrid
widget does not have a selectedrow/s properties so can it be done via another mechanism?
Many Thanks,
Paul
