Re: multizone js xhr response
Ah, you're right. You can't add script during the action phase, you
need to add the script when the zones are rendering.
Try this:
@Inject
private RenderSupport _support;
@Inject
private PageRenderQueue _queue;
MultiZoneUpdate onHello() {
_queue.addPartialMarkupRendererFilter(new
PartialMarkupRendererFilter() {
public void renderMarkup(MarkupWriter writer, JSONObject
reply, PartialMarkupRenderer renderer) {
_support.addScript(alert('I am script'););
renderer.renderMarkup(writer, reply);
}
});
return new MultiZoneUpdate(test, _timeBlock);
}

I am creating the Ajax.Request myself as this is essentially what the
Autocompleter does which is the best example I can find. I am infact
extending the Autocompleter so that I can trigger an Ajax communication when
an item is selected from the autocomplete suggestions. Essentially this is
the same as having an actionlink, in that I am using
ComponentResources.createEventLink().toAbsoluteURI() to determine the URL to
call via Ajax.Request. The listener on the other end returns the
MultiZoneUpdate.
I've tried injecting RenderSupport:
@Inject private RenderSupport renderSupport;
But the following exception is thrown:
Caused by: java.lang.RuntimeException: No object of type
org.apache.tapestry5.RenderSupport is available from the Environment.
Available types are
org.apache.tapestry5.services.ComponentEventResultProcessor.

I believe this is because it's invalid in the context of a partial render
(ajax server side event listener). Have you tried injecting RenderSupport
and using it in your example 'Object onActionFromUpdate()' ? I don't think
it would work, because it is essentially the same architecture as what I
have, minus the actionlink component.

I'm not sure I follow why you need to create your own Ajax.Request
instead of using one of the built-in action/event link components. You
can give it the name of one zone but return a MultiZoneUpdate
response.
(from tapestry core MultiZoneUpdateDemo.tml )
t:actionlink t:id=update zone=fredupdate/t:actionlink
(from tapestry-core MultiZoneUpdateDemo.java)
Object onActionFromUpdate()
{
return new MultiZoneUpdate(fred, fredBlock).add(barney,
barneyBlock).add(dino, His dog, Dino.);
}
Now I need to add the ability to execute a script, generated (or values
populated) by the server.
@Inject RenderSupport and call the addScript methods. If you're using
the built-in components then they get handled by default. The code
that does that is in ZoneManager.processReply.
Is this what you are trying to do?

Re: multizone js xhr response
I've found where the JSON is built, and can't see a way to include a
script call anywhere in there.
So my first hacky inclination is to create a hidden zone who's innerHTML
will contain the javascript (which has been updated in the server side
event listener, and call it via something like
'eval(zone.element.innerHTML);'.
In order to get this to work, I need to understand tapestry.js
ZoneManager.show:
show: function(content)
{
this.updateElement.update(content);
var func = this.element.visible() ? this.updateFunc : this.showFunc;
func.call(this, this.element, this.endcolor);
this.element.fire(Tapestry.ZONE_UPDATED_EVENT);
},
1. updates the innerHTML
2. then runs the show or update effect
3. fires Tapestry.ZONE_UPDATED_EVENT.
Therefore the most sensible place for me to place my handling code is in
an event listener for Tapestry.ZONE_UPDATED_EVENT. Does anyone know
how to attach a listener for this event?

Re: multizone js xhr response
I've answered my own question:
Tapestry.onDOMLoaded(function(){
$(jsZone).observe(Tapestry.ZONE_UPDATED_EVENT, function(event){
/ find inner html and eval
});
});
this does work ok, however I'm suspicious that there's an easier/tidier
way to achieve the same already built in to tapestry...
???
