I have an XML I am sending to an operation from a BPL.  This is a query for Patient information from Epic using a web service.  I created the operation using the add-in in Studio.  I setup the BPL to do a Call and send whatever data I receive from the client.  I get a response back from Epic with a list of matching Patients.  In the BPL I am trying to use the Response Builder to pass the response ID, name, DOB, etc. to matching context items to then pass to the client as a response.  I get the following error within the call:
ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zOnResponse1+2 ^FCH.BPL.PATWISJSONEPICXML.Context.1 *IDs,%Collection.ListOfObj -- logged as '-'
number - @''
  From what I can tell the IDs is in the definition but because the response can be multiple responses that I need to handle it.  I am stuck on how I need to setup the context items and/or how to read the response when there is the possibility of multiple responses.
