Dear all,

I have a very basic question about AJAX in Tapestry 4.1.3: IIUC, the "updateComponents" attribute provided by Tapestry components works by rendering the *whole* page, extracting the relevant components (via their ids) and sending them back to the client.
I find this very elegant and it makes the pages easy to maintain.

For very complex pages, however, the above approach can result in some overhead. I'd therefore like to just call a function that returns the replacement div (and
does not render the whole page).

Is there a simple example that shows how to do this?

For instance: Given a div and a link, clicking the link will replace the div via AJAX
without reloading the page.

Thanks,
Kaspar

P.S. I have started reading about EventListeners but am not sure whether this is
exactly what I need.
