Long story short, I have taken a standard blue print and recreated it in the advanced services creating actions for all the XML and I have things working great from a VCO point of view so I adding the request for a catalog item as an advanced service and what I am really looking for is how to get the value of the person that is logged and requested this service to use as the owner. I would really like to have it pre-populate as well as be able to be able to search for others but so fat I have not been successful when trying to change the value of the owner field to use external action to get current user but I have found when the requests are made they are made from service accounts and such.
So what am I missing or need to do in the form designer to pull the current vCAC logged in user to the owner field? Inquiring minds need to know 
Thanks
