If you only need to get HTML on the client and not on the server-side,
then you may just use Tapestry's built-in logic for handling AJAX requests.
On the server side create eventLink:
Link link = resources.createEventLink(eventType, contextValues);
return link.toAbsoluteURI();
Pass this link to client side during rendering and when needed do the AJAX
calls using, say, jQuery.ajax.
You may handle ajax request on the server side the same way I wrote in my
example above --
return block from event handler or use ajaxResponseRenderer.addRender().
On the client-side response will be the same JSON and you may extract
content from it.
Note that in both cases it is possible to render multiple blocks by one
request -- this is if you call
ajaxResponseRenderer.addRender() multiple times.
