Going through nodeStamp of an af:tree

Question

Hi Folks,
I have a mission that I was not able to solve.
I have a tree that shows Employees and Subordinates. One Subordinate can be inside one or more Supervisors.
When the user clicks on any subordinate, the icon of all supervisors of that subordinate have to change.
I searched some code and see that I could work with JUCtrlHierNodeBinding and try to solve it but that is not my case.
When I get the treeModel and try to convert it to JUCtrlHierNodeBinding, I get a convert exception because I am not using DataBinding at all.
Does anybody could help me?
Thanks in advance.
Best Regards,
Ricardo Morais

Hey Frank,
I have no binding at all.
I have only a TreeModel that is populated by a list of users and each user has its subordinates.
I am using the Backing Bean to call the EJB and populate a list.
How can I do a workaround on it?
public void createTree(DisclosureEvent event) {
RichTree table = (RichTree)event.getComponent().findComponent("treeEC");
if (table != null) {
RowKeySet disclosedRowKeySet = table.getDisclosedRowKeys();
if (disclosedRowKeySet != null) {
disclosedRowKeySet.clear();
AdfFacesContext.getCurrentInstance().addPartialTarget(table);
estruturaComercialSelecionada = null;
pararBuscaRecursiva = false;
//Somente quando vamos para a tab
if (event.isExpanded()) {
try {
PontoDeVendaFacade pontoDeVendaFacade = (PontoDeVendaFacade)ServiceLocator.getInstance().getEJB(PontoDeVendaFacade.class);
List<EstruturaComercialEntity> ec = pontoDeVendaFacade.selecionarAglutinadoresCorporativos(getUsuarioLogado());
treeModel = new ChildPropertyTreeModel(ec, "estruturasComerciaisFilhas");
arvoreAuxiliarEstruturasComerciais = ec;
} catch (Exception e) {
logger.error(e.getMessage(), e);
handleException(e);
