Refreshing the JUTreeNodeBinding when we use whereclause with the view

Question

Hi There,
I am facing a problem with refreshing the JUTreeNodeBinding after adding a whereclause to the underlying view object. I have a BC4J view object for a database table which has a parent-child relationship between the rows. This is established using a VL between the same view. Now on click of a button we add a whereclause to the view object (parent/source view object). Lets say it appends a whereclause like:
QRSLT (where deleted = true)
And then I execute the query for the underlying view object. It refreshes the 1st level nodes accordingly. But the child nodes remains as it is and the whereclause application is not reflected. I have tried finding the VL and then getting the destination end (a view object) and setting the whereclause for it followed by an execute query on the same. This does not affect the child nodes. I have tried traversing through all the nodes and getting the user objects using ((JUTreeNodeBinding)node.getUserObject()) and tried refreshControl() as well.
  private void executeDestinationQuery(ViewObject vo, String viewLinkName, String whereClause)
    ViewLink vl = vo.getApplicationModule().findViewLink(viewLinkName);
    ViewObject destVo = vl.getDestination();
    destVo.setWhereClause(whereClause);
    destVo.executeQuery();
    private void executeQueryOnChildNodes(JUTreeNodeBinding nodeBinding)
      nodeBinding.refreshControl();
      java.util.List children = nodeBinding.getChildren();
      if(children != null)
        for(Iterator childrenItr = children.iterator(); childrenItr.hasNext();)
          executeQueryOnChildNodes((JUTreeNodeBinding)childrenItr.next());
    }

Hi,
Do you use ADF binding ? If yes, why do you refresh the tree node on teh business service and not the binding layer, in which case the UI would be refreshed accordingy ?
