On an Ajax request, if you return a component or block from an event
handler method, Tapestry will render the result as a JSON reply,
putting the markup inside a "content" key. I'm still working on
handling errors nicely, and handling the case where additional
JavaScript is generated as part of the render. All of this is
fundamental to the Zone component support.
Don't forget that you can check Request.isXHR() to see if the request
is Ajax or traditional.
