How can I display a message while the tree is loading it's data from the server? Are the onXLS and onXLE events required for that?

Thanks,

Using those two events is most common approach

In simple case, when you not using dynamic loading, it can be done without events as

    var tree = new...
    ...
    show_loading_message();
    tree.loadXML(url,function(){
       hide_loading_message();
    });
