How to fetch work item parent?

Given a workitem, you would search its references for 'Parent' links,
and use the handle of the workitem on the other end of the parent link.

here is how I do it for Dependancies.. (in an OperationAdvisor)

					IWorkItemReferences iwr = ((ISaveParameter) data).getNewReferences();

					// and only the depends on links

					List<IReference> wir = iwr.getReferences(WorkItemEndPoints.DEPENDS_ON_WORK_ITEM);

               // loop thru the workitems this one depends on

               for(int j=0;wir!=null && j<wir.size();j++)

               {

	             if(Debug) System.out.println("looping thru references");

                     // if this is to an item.. should always be

                     if(wir.get(j).isItemReference())

                     {	

                             // get the item, and it SHOULD always be a workitem

                             IWorkItem r = iac.resolveAuditable(

                             (IWorkItemHandle)wir.get(j). 

                             resolve(),IWorkItem.FULL_PROFILE, null);
