How to invoke BPM object instance variable from interactive activity?

Question

I have a screenflow with an automatic activity "A" followed by an interactive activity "B". "B" calls a BPM object "X" and uses a JSP presentation to show its attributes. Is there a way to use another BPM object, say type "Y", create an instance variable of that type inside "A", and get its attributes values from the JSP page associated to "B"?

Try this. It assumes you have:
<li> a user named "auto"
<li> a project variable named "customerType"
<li> an instance variable named "orderAmount" that is a decimal
<li> an instance variable named "order" that is a BPM Object that has attributes named "customerName" and "amount"
ps as ProcessService
xmlObject as Fuego.Xml.XMLObject
do 
  connectTo ps
      using url = Fuego.Server.directoryURL,
      user = "auto",
      password = "auto"
  instF as InstanceFilter
  create(instF, processService : ps)
  addAttributeTo(instF, variable : "customerType", comparator : IS, value : "Gold")
  instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS)
  for each inst in getInstancesByFilter(ps, filter : instF) do
    // here's how to get the value inside a primitive instance variable
    orderAmtObj as Object = getVar(inst, var : "orderAmount")
    // here's how to get the value of attributes inside a complex BPM Object instance variable
    //    - in this case this is an "order" object with two attributes (customerName and amount)
    orderObj as Object = (getVar(inst, var : "order"))
    xmlObject = Fuego.Xml.XMLObject(createXmlTextFor(DynamicXml, object : orderObj, topLevelTag : "xsi"))
    logMessage "The value of the order object's customer name is: " +
           selectString(xmlObject, xpath : "customerName")
    logMessage "The value of the order object's order amount is: " +
           selectNumber(xmlObject, xpath : "amount")
    // here's a rather uninspired way to retrieve who the participant is that was assigned the instance
    logMessage "The participant assigned to this instance is: " + inst.participantId
  end
on exit
  disconnectFrom ps
endDan
