Is there a Project Area Id? (PlainJavaAPI)

I failed to find a function named "findProjectAreaById()" on PlainJavaAPI, so I decide to make one. If it already exists please read no further and just tell me where I get it :)

So, I'm trying to build a dynamic query, which I think it's faster (Am I right?). I build this piece of code:

	private IProjectAreaHandle findProjectAreaById(UUID id) throws TeamRepositoryException {

		ProjectAreaQueryModel pArea = ProjectAreaQueryModel.ROOT;

		IItemQuery query = IItemQuery.FACTORY.newInstance(pArea);	

		

		IPredicate predicate = pArea.itemId()._eq(query.newUUIDArg());

		query.filter(predicate);

		Object[] parameters= new Object[] {  IProjectArea.ITEM_ID_PROPERTY, id };



		ItemQueryIterator<IProjectAreaHandle> iterator = new ItemQueryIterator<IProjectAreaHandle>(getAuditableCommon(), query, parameters);

		if (iterator.hasNext(null)) {

			return iterator.next(null);

		} else {

			return null;

		}

	}

I call it on something like

IProjectAreaHandle projectHandler = findProjectAreaById(UUID.valueOf(areaId));

Where areaId is a string previously obtained with:
ProjectArea.getItemId().getUuidValue();

But I get "Incorrectly typed parameter submitted to query; Parameter 0 was class java.lang.String but com.ibm.team.repository.common.UUID was expected"


How is the UUID calculated?

I didn't found a way to convert com.ibm.team.repository.common.UUID into something standard and back to com.ibm.team.repository.common.UUID. Is the UUID generated from ProjectArea name?


I have found an ProjectAreaQueryModel.ROOT.uniqueName() that I could use on query, but I didn't found the associated IProjectArea property id.

Resuming, how can I store an unique identifier for a ProjectArea, and later recover that ProjectArea based on that unique identifier?
