Stale Data problem in plain client

Hi,
I have a bit of code that will run a saved query every minute which looks for workitems with a specific tag. The code will then perform an action and remove the tag. This works perfectly except for one little problem. If I manually re-add the tag to the workitem just processed, the routine fails when attempting to save the workitem with a stale data problem:-

com.ibm.team.workitem.common.model.MultiStaleDataException: Stale Data

	at com.ibm.team.workitem.common.internal.util.Utils.checkSaveResult(Utils.java:282)

	at com.ibm.team.workitem.client.internal.WorkItemWorkingCopyRegistry.saveWorkItems(WorkItemWorkingCopyRegistry.java:1741)

	at com.ibm.team.workitem.client.internal.WorkItemWorkingCopyRegistry.saveAffected(WorkItemWorkingCopyRegistry.java:1637)

	at com.ibm.hursley.cicsts.test.ste.regression.scheduler.WorkItemScheduler.run(WorkItemScheduler.java:69)

This is an abstract of the code I am using:-

		IQueryResult<IResult> results = queryClient.getQueryResults(runquery);

		results.setPageSize(500);

		results.setLimit(Integer.MAX_VALUE);



		List<IWorkItemHandle> workitemhandles = new ArrayList<IWorkItemHandle>(results.getResultSize(null).getTotal());



		System.out.println("Query returned " + results.getResultSize(null).getTotal() + " work items");



		while(results.hasNext(null)) {

			IResult result = results.next(null);



			workitemhandles.add((IWorkItemHandle) result.getItem());

		}

private List<IWorkItem> retrieveWorkItems(List<IWorkItemHandle> workitemhandles) throws TeamRepositoryException {

		List<IWorkItem> listWorkItems = repository.itemManager().fetchCompleteItems(workitemhandles, IItemManager.DEFAULT, null);



		System.out.println("Retrieved " + listWorkItems.size() + " work items");





		return listWorkItems;

	}

	private void addComment(IWorkItem workitem, String comment, boolean addScheduledTag)  {

		System.err.println("W" + workitem.getId() + "Adding comment " + comment);

		IWorkItemClient workItemClient = (IWorkItemClient)repository.getClientLibrary(IWorkItemClient.class);

		

		IWorkItemWorkingCopyManager workingCopyManager = workItemClient.getWorkItemWorkingCopyManager();

		try {

			workingCopyManager.connect(workitem, IWorkItem.FULL_PROFILE, null);

		} catch (TeamRepositoryException e) {

			e.printStackTrace();

		}

		WorkItemWorkingCopy workingCopy = workingCopyManager.getWorkingCopy(workitem);

		

		IComments comments = workingCopy.getWorkItem().getComments();

		IComment newComment = comments.createComment(repository.loggedInContributor(), XMLString.createFromPlainText(comment));

		comments.append(newComment);

		

		removeRequestedTag(workingCopy);

		if (addScheduledTag) {

			addSceheduledTag(workingCopy);

		}



		IDetailedStatus status = workingCopy.save(null);

		if (!status.isOK()) {

			System.err.println("Failed to save workitem : " + status.getDetails());

		} else {

			System.err.println("Saved Data");

		}

			

			

		return;

	}

How do I ask the client to dispose of the cached workitem or tell it to refresh it so that I don't get the stale data problem?
