How to get work item details programatically ?

Question

Hi All,
I have a list of work items (process instances) and I want to retrieve each item details such as: attachments, notes, id, ...
All the items are filtered and represented as Fuego.Papi.Instance:
Fuego.Papi.Instance[] inst = busProcess.getInstancesByFilter(filter : instFilter);
But the work item details are inherited from Fuego.Lib.ProcessInstance. So, how to get the item details from inst[] ?
Would appreciate any help, may be Dan will have an advise ?
Regards,
Kim

If you have instances returned by your filter, you could extract variable information for each instance by doing something like this:
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
endInside the above "for" loop, you could retrieve these predefined variables (this example assumes you use "inst" in your "for" loop):
    objRet as Any
    objRet = inst.getVar(var : "PREDEFINE_ACTIVITY")
    logMessage "Activity name = " + objRet using severity = DEBUGSubstitute "PREDEFINE_ACTIVITY" in the above logic to get this information:
PREDEFINE_PRIORITY (priority)
PREDEFINE_ACTIVITY_DEADLINE (activity.deadline)
PREDEFINE_CREATION_TIME (creation.time)
PREDEFINE_PROCESS_DEADLINE (deadline)
PREDEFINE_DESCRIPTION (description)
PREDEFINE_PROCESS (process)
PREDEFINE_RECEIVED_TIME (receptionTime)
PREDEFINE_PARTICIPANT (participant)
PREDEFINE_COPY (id.copy)
PREDEFINE_STATUS (status)
Similarly, you might want to try to get instance information using the Fuego.Papi.VarDefinition object a try. Never used it, but the logic might be as simple as:
    logMessage "who created? = " + inst.getVar(Fuego.Papi.VarDefinition.CREATOR_ID) using severity = DEBUG
    logMessage "does it have attachments? = " + inst.getVar(Fuego.Papi.VarDefinition.HAS_ATTACHMENTS) using severity = DEBUG   
    logMessage "does it have notes? = " + inst.getVar(Fuego.Papi.VarDefinition.hasnotes) using severity = DEBUGDan
