jQuery Grid Plugin - jqGrid

Hi

I am current evaluating this grid and so far impressed with its capabilities.  I have come across an issue whihch I am sure is developer related and not an actual bug.

I need to use th ehierarchy function and have the following defined:

Two data sources - one for the master and one for the detail.  Two grids with the hierarchy mode set correctly.  When I run the application I get the first grid displayed correctly, I then click the + option and I am expecting to see the second grid appear which it does but it has no data.  I have debugged this and have found that the OnDataRequesting call is made to the code behind which is excellent since I can get to the right key to correctly bind my second grid.  However what I am finding is that a second call is being made to the service that I have defined in my datasource Tests and this is passing up a value of 0 in the parameters which then negates the binding.  I have put my code in below, I searched to see if I was doing something wrong in the datasource and both appear to be correctly configured. 

Any help would be appreciated.

The code on the ASPX page is as follows

public void JQGrid2_DataRequesting(object sender, JQGridDataRequestEventArgs

e)

{

ScenarioService service=new ScenarioService

();

service.ListTests(

Convert

.ToInt64(e.ParentRowKey));
