My main data source has a group that I would like to prepopulate from
my secondary data source (referencedata.xml) when the form loads.

I'm not too familiar with JScript, but this is what I've tried:

XDocument.DataObjects("referencedata").QueryAdapter.Query();  // is
this needed?
var refdata = XDocument.GetDOM("referencedata");

var runs = XDocument.DOM.selectSingleNode("//runs");
runs = refdata.selectSingleNode("//runs");

I think the problem is in the last line since in the debugger, refdata
looks like it's is loaded correctly.  Can I not simply copy nodes like
this?  Is there another function I need to use?

Thanks,
Will
