This page was set up using a traditional Tapestry approach, which is to use the pageBeginRender() method.
In this approach, the caller activates this page, then just before Tapestry renders the page Tapestry will call
our pageBeginRender() method. It does this because we implemented PageBeginRenderListener. So the pageBeginRender()
method is a place where we can set up the things we want on the page, eg. we call setMessage(...).
