Using Infoengine for retrieving workflow task information

Using Infoengine for retrieving workflow task information

I am curious if someone has done this. It does not look like it is straight forward using infoengine. So wondering, if anyone has used infoengine to get workflow intruction, variables, and voting options of an open task.

thanks.

I don’t know your exact requirement to use info engine to get workflow activity information.

I had similar requiring for one cognos report, where I have to use info engine to get workflow related information using info Engine.  It’s tedious to write webjects to retrieve all workflow related information when you have API’s easily available. I wrote one helper class to retrieve all require information using API. Call helper class from task/xml file, which with return result in infoengine group.

So you can use the xml/task for cognos reports, web service or for any other purpose.

Below is example

<ie:webject name="Create-Group" type="GRP">

    <ie:param name="GROUP_OUT" data="out"/>

</ie:webject>

<%

System.out.println("***************IN TASK ********************");

Group out = getGroup( "out" );

String oID=getParam("objectID").toString();

Group group=ext.report.SummaryReport.getDescription(oID);

Element[] elements = group.getElementArray();

for (int i = 0; i < elements.length; i++) {

    Element e= (Element) elements[i];

    out.addElement ( e );

}

System.out.println("*************** out summary Header********************");

%>

<ie:webject name="Return-Groups" type="GRP">

<ie:param name="GROUP_IN" data="out"/>

</ie:webject>

public static Group getRoutingHistory(String objectID) {

  System.out.println("WithoutRepeter");

  Group grp = new Group();

  try {

  ReferenceFactory rf = new ReferenceFactory();

  WTReference ref = rf.getReference(objectID);

  WTChangeRequest2 wtChangeRequest2 = (WTChangeRequest2) ref.getObject();

  Enumeration processes = WfEngineHelper.service.getAssociatedProcesses(wtChangeRequest2, null);

  while (processes.hasMoreElements()) {

  WfProcess process = (WfProcess) processes.nextElement();

  NmOid nmOid = new NmOid(process);

  QueryResult status = WorkflowCommands.getRouteStatus(nmOid);

  while (status.hasMoreElements()) {

  Object obj = status.nextElement();

Hi,
Could please add the getAuditEvent() method in reply with workitem parameter

It will be very helpfull to get all the details for different objects of change management.
