Tree item select event not working with @GxtUiHandler

[GoogleCodeExporter]

I am trying to get @GxtUiHandler to work with either 'Select' or 
'SelectionChanged' event on TreePanel.

I have done this successfully with:
tree.getSelectionModel().addSelectionChangedListener(
     new SelectionChangedListener<ModelData>() {
   @Override public void 
        selectionChanged(SelectionChangedEvent<ModelData> se) {
            ModelData md = se.getSelectedItem();
             etc...
        });

But this (and various other combinations/permutations) does not work:
@GxtUiHandler(eventType=GxtEvent.SelectionChange, uiField={"tree"})
    public void handleSelection(TreePanelEvent<BaseTreeModel> tpe){
    BaseTreeModel btm = tpe.getItem();
    String name = btm.get(NAME_FIELD);
    fireSelectedHandlers(name);

    System.err.println("selected " + name);
    }

Also, this works on TreePanel for CheckChange events:
@GxtUiHandler(
              eventType = GxtEvent.CheckChange, 
              uiField = { "tree" })
public void handleCheck(TreePanelEvent<BaseTreeModel> be) {
    ModelData md = be.getItem();
    BaseTreeModel btm = be.getItem();
    String name = md.get(NAME_FIELD);
    boolean checked = be.isChecked();
    String checkedTxt = (checked?"checked":"unchecked"); 
    System.err.println( name +" was " + checkedTxt);
    if(btm.getChildCount()>0){
        System.err.println(" has children ");
    }
}

any thoughts on why this is not working (I am not getting to the breakpoint at 
first line in handler method.

It looks like the problem is the fact that this isn't binding the listener 
directly on the TreePanel (the widget configured in the UiBinder XML with 
ui:field), which is what is supported with @GxtUiHandler.  This, however, 
requires adding the SelectionChangedEvent handler on the SelectionModel.

I'll have to consider how this could be done easily.

Changing type to Enhancement as using @GxtUiHandler on a widgets SelectionModel 
is not currently supported.  Only adding event handlers directly to widgets in 
the UiBinder is supported.
