Remove "renderTreeOn: html", you should never all render methods of
other components. And since this method returns the component, it is
displayed twice.

Yes, but it is probably not simple and certainly involves changing the
implementation of WATree. You could do it using JavaScript, e.g. with
script.aculo.us and a scroll-to effect.
