Query vCloud Object from vCO

Hi,

I am wondering if anybody can help me.

I am trying to query vCloud for both a vCloud:vAppTemplate and a vCloud:Vdc object. The only input parameter I have at the moment is a string containing the vAppTemplate Name and the Org VDC Name.

Is this possible using the built in methods in the vCloud 1.5 Plugin for vCO?

I can see various query methods but am no Javascript/vCO exprt so am trying to figure out how I would be able to return an actual recognised Type. I need to update a workflow attribute with the output, so that it can be used to instantiate a vApp template.

Any help is much appreciated

Thanks
