Treepanel : The grandparents of selected tree node is NULL

[B.Oury]

Hi,
I've a problem when I click on a node with depth 2, I can't recover its grandparents, there is null.

  TreeStore<BeanModel> objStore = new TreeStore<BeanModel>();
  TreePanel<BeanModel> objTree = new TreePanel<BeanModel>(objStore);

objTree.getSelectionModel().addListener(Events.BeforeSelect, new Listener<SelectionEvent<BeanModel>>() {

      @Override
      public void handleEvent(SelectionEvent<BeanModel> be) {
        AgdRdvDTO selectAppointment = null;
        AgdDemandeDTO selectDemande = null;
        AgdSuiviDTO selectSuivi = null;

        TreePanelSelectionModel<BeanModel> tree = (TreePanelSelectionModel<BeanModel>) be.getSource();
        BeanModel item = be.getModel();
        if (item.getBean() instanceof AgdDemandeDTO) {
          selectDemande = item.getBean();
        } else if (item.getBean() instanceof AgdSuiviDTO) {
          selectSuivi = item.getBean();
          selectDemande = objStore.getParent(item).getBean();
        } else if (item.getBean() instanceof AgdRdvDTO) {
          selectAppointment = item.getBean();

          BeanModel beanSuivi = objStore.getParent(item);
          selectSuivi = beanSuivi.getBean();
          BeanModel grandParents= objStore.getParent(objStore.getParent(item));
          if (grandParents!= null) {
            selectDemande = grandParents.getBean();
          }
          AgendaEventBus.getEventBus().fireEvent(new SelectDetailEvent(selectDemande, selectSuivi, selectAppointment));
        }
      }
    });

The first time I clicked, grandParents is initialized and if i clicked on an other item of the same parent, the grandParents is always null.

Thanks for your help

You should try get the store reference everytime you need it. May be one update/load has changed it. Therefore your reference does not reflect what is actually in it.

tree.getStore() instead of using objStore

I meant:
objectTree.getStore()
