Hierarchy Viewer and Drag Drop

Question

Hi I am new for ADF Hiearchy Viewe components. I am trying drag from ADF table rows to drop ADf Hierarchy viewer node and introduce by http://docs.oracle.com/cd/E28280_01/web.1111/b31973/dv_hviewer.htm here.
1. can get selected rows from drag source ADF rich table and I couldn't get Drop Row Key. In my source some hierarchy node work and some are not work. sourc here.
<pre>
    public DnDAction toDropListener(DropEvent event)
        RichTable table = (RichTable) event.getDragComponent();
        Transferable t = event.getTransferable();
        DataFlavor<RowKeySet> df = DataFlavor.getDataFlavor(RowKeySet.class, "rowmove");
        RowKeySet rks = t.getData(df);
        Iterator iter = rks.iterator();
        List<Row> sourceRow = new ArrayList<Row>();
        while (iter.hasNext())
            List key = (List) iter.next();
            table.setRowKey(key);
            JUCtrlHierNodeBinding rowBinding = (JUCtrlHierNodeBinding) table.getRowData();
            sourceRow.add((Row) rowBinding.getRow());
        Transferable transferable = event.getTransferable();
        DataFlavor<Object> dataFlavor = DataFlavor.getDataFlavor(Object.class);
        Object transferableObj = transferable.getData(dataFlavor);
        if (transferableObj == null)
            return DnDAction.NONE;
        UIComponent dropComponent = event.getDropComponent();
        Object dropSite = event.getDropSite();
        if (dropSite instanceof Map)
            String clientRowKey = (String) ((Map) dropSite).get("clientRowKey");
            Object rowKey = getRowKey(dropComponent, clientRowKey);
            List<Key> keys = (List<Key>) rowKey;
            System.out.println("Row Key: "+rowKey+ " Size of Keys: "+keys.size());
            if (rowKey != null)
                DCIteratorBinding itrEmp;
                if(keys.size()==1)
                    itrEmp = ADFUtils.findIterator("ParentEmpTreeVO1Iterator");
                }else
                    itrEmp = ADFUtils.findIterator("ChildEmpTreeVO1Iterator");
                ViewObject hist=itrEmp.getViewObject();
                Key key = keys.get(keys.size() - 1);
                Row targetRow = hist.getRow(key);
                System.out.println("Key: "+key);
                System.out.println("Employee Id: " + targetRow.getAttribute("EmpId"));
                if (sourceRow != null && !sourceRow.isEmpty())
                    for (Row row : sourceRow)
                        Row newRow=itrEmp.getRowSetIterator().createRow();//hist.createRow();
                        newRow.setAttribute("EmpId", row.getAttribute("EmployeeId"));
                        newRow.setAttribute("FirstName", row.getAttribute("FirstName"));
                        newRow.setAttribute("ManagerId", targetRow.getAttribute("EmpId"));
                        itrEmp.getRowSetIterator().insertRow(newRow);//hist.insertRow(newRow);
                        System.out.println("Created Row.");
            else
        RequestContext.getCurrentInstance().addPartialTarget(event.getDropComponent());
        return event.getProposedAction();
    private Object getRowKey(UIComponent component, String clientRowKey)
        if (component instanceof UIHierarchyViewer)
            UIHierarchyViewer hv = (UIHierarchyViewer) component;
            ClientRowKeyManager crkm = hv.getClientRowKeyManager();
            return crkm.getRowKey(FacesContext.getCurrentInstance(), component, clientRowKey);
        return null;
</pre>
and in hierarchy viewer added row displayed on level one for session then reload page it is ok why shot in level 1
Where I missed? how to Selected rows assign to hierarchy viewer object? thanks juddi

thanks for your reply shay. i am just trying to understand how a dvt HV could render in iPhone mobile browser (eg. iOS simulator) as its a part of ADF Faces components. as a part of mobile development we have only trinidad components available (not HV) and it renders in iOS simulator.
I have tested a HV app (JDev 11.1.1.6) in Safari web browser and it works fine there. Please share your thoughts on this.
