[newbie] EventListener in Tapestry 5 ?
Is something like that:
http://tapestry.apache.org/tapestry4.1/ajax/EventListener.html
in Tapestry 5 ?
I can't see @EventListener annotation in Tapesty5.

I don't see the need for DWR for implementing something that Tapestry
doesn't implement out-of-the-box. I have one example, but its written in
Portuguese.
Solution outline:
1) Define an event name.
2) In your page, component or mixin class, @Inject ComponentResources and
use its createEventLink() to create a link that will trigger that event.
3) Still in the same class, create a method with @OnEvent("yourEventName")
that handles the event and returns a JSONObject or JSONArray.
4) @Inject RenderSupport and use its addScript() method to generate any
needed initialization for your JavaScript code, including the event URL.
5) If you use Prototype, use Event.observe('elementId', 'eventName',
function() { implement your handling here ; }) to listen to the event and
invoke the event method usint its URL. You'll probably use Ajax.Request.
transport.responseJSON is exactly the JSONObject or JSONArray you returned
in your event handler method.
A simple template you can use, based in real code, follows. It reacts to a
change in a select tag, posts its value, gets the response as a JSON
object and the changes the value of some <span>s with the object
properties.
/* This URL is the one created by ComponentResources.createEventLink().
This is the function which is invoked by the JavaScript line added via
RenderSupport.addScript().
*/
function initialize(url) {
Event.observe('selectId', 'change', function() {
new Ajax.Request(url, {
method : 'post',
parameters: { value: $F('selectId') },
onSuccess: function(transport) {
var result = transport.responseJSON;
$('span1').innerHTML = result.property1;
$('span2').innerHTML = result.property2;
$('span3').innerHTML = result.property3;
}
});
});
}
I hope it helps.

Well, if you want Mouse and Text field (key press events), use Java Script
on the client side, its very useful and efficient. If you're very
particular, use DWR to map JS events to a Java Class @ server side, but with
in-built ajax support, Tapestry doesn't require it though.
Protoype can help u with JS: http://www.prototypejs.org/api/event

It is.
Add this to your page/component class:
@OnEvent @Log public void onEvent() {}
and watch the log file for the stream of events that are fired against this
(catch-all) event handler.

Thanks:)
But... I see, that is a addition to tapestry. Why is not in native Tapestry
5 ? :(
