    void getRolesMenuAccess() {

        String roleId = (String) Sessions.getCurrent().getAttribute("roleId");
        TreeNodeDataBase tndb = new TreeNodeDataBase();
        List menuRoleIdLst = new ArrayList();
        menuRoleIdLst =tndb.getUsersRoles(roleId, "");

        Treechildren tc = tree.getTreechildren();
        Collection<Treeitem> lista = tc.getItems();
        Iterator it = lista.iterator();

        //while (it.hasNext()){

            //Treeitem treeitem = it.next();
            //logger.info("sssssssss "+ treeitem.getId());
