CellTree with SingleSelectionModel will not fire event for root node (GWT 2.3)

[Jens]

Hi

I have a CellTree with a SingleSelectionModel, when i click the root
node it gets visually selected but does not fire a
SelectionChangeEvent, the problem is only for the root element.

Has anyone else discovered (is it by design / a bug / me that screwed
up).

My example is quite simple but i cannot post the code as is, but i can
clean it up and post it if required.

Best regards Jens

Anyone? I'm trying to create an 'windows explorer' like interface with
a CellTree on the left and a CellTable on the right (so when i click
on a node in the tree i get the details in the table). It works nicely
except that i can not click the root node. Its a bit of a showstopper.

Best regards Jens

Hi

Thanks for the tip, but my problem is not loading the nodes, its only
selection the root node that causes me problems (or did i miss
something in the mentioned thread?).

Best regards Jens

Yes, it's the end of the code:

 // defining
  private SingleSelectionModel<MyType> selectionModel =
    new SingleSelectionModel<MyType>();

  // inside TreeViewModel ctor (or in a better place)
  selectionModel.addSelectionChangeHandler(new SelectionChangeEvent.Handler() {

    public void onSelectionChange(SelectionChangeEvent event) {
      // fire rpc, a place change or something else
      // event.getSelectedObject() contains the selected element
    }
  });

  // return the DefaultNodeInfo with info about the selection strategy
  public <T> NodeInfo<?> getNodeInfo(T value) {

    // do something with the value and return the right DefaultNodeInfo
    if(value instanceof MyType1) {
      return new DefaultNodeInfo<SectionDTO>(
          new SectionDataProvider(),
          new MyCustomCellOrADefaultOne(),
          selectionModel,
          null);
    }
    else if ...
  }
