Thiago,
FYI here's my latest version of my MultiZoneUpdate helper, updated for
t5.2 renamed to XHRResponseHelper:
public class XHRResponseHelper
{
private HashMap<String, Object> zoneUpdates;
public XHRResponseHelper()
{
this.zoneUpdates = new HashMap<String, Object>();
}
public void addScriptCall(final String script, PageRenderQueue
pageRenderQueue, final JavaScriptSupport javascriptSupport)
{
pageRenderQueue.addPartialMarkupRendererFilter(new
PartialMarkupRendererFilter()
{
public void renderMarkup(MarkupWriter writer, JSONObject
reply, PartialMarkupRenderer renderer)
{
javascriptSupport.addScript(script);
renderer.renderMarkup(writer, reply);
}
});
}
public void addZoneUpdate(String zoneId, ComponentResources
componentResoures)
{
addZoneUpdate(zoneId,
componentResoures.getEmbeddedComponent(zoneId));
}
private void addZoneUpdate(String zoneId, Object renderer)
{
zoneUpdates.put(zoneId, renderer);
}
public MultiZoneUpdate buildMultiZoneUpdate()
{
MultiZoneUpdate mzu = null;
for (Entry<String, Object> entry : zoneUpdates.entrySet())
{
if (mzu == null)
mzu = new MultiZoneUpdate(entry.getKey(),
entry.getValue());
else
mzu.add(entry.getKey(), entry.getValue());
}
return mzu; // null if zoneUpdates is empty
}
}
It can be used like so:
@Inject
private PageRenderQueue pageRenderQueue;
@Inject
private JavaScriptSupport javascriptSupport;
@Inject
private ComponentResources componentResources;
MultiZoneUpdate onSelectItem(String identifier)
{
XHRResponseHelper xrh = new XHRResponseHelper();
xrh.addScriptCall("alert('selected " + identifier + "');",
pageRenderQueue, javascriptSupport);
xrh.addZoneUpdate("myZone", componentResources);
return xrh.buildMultiZoneUpdate();
}
The tapestry resouces pageRenderQueue, javascriptSupport and
componentResources are passed in as parameters to each method since they
are environmental services and the XHRResponseHelper may be contributed
to by embedded components as well.
will log jira issues for consideration now.

As far as I know, when you return a MultiZoneUpdate, the value passed
to the zone parameter is completely ignored, so there's no need to
create a dummy zone.
really? i thought a valid zone was required to initiate the ajax
request (in the current methodology).
A valid zone is needed for MultiZoneUpdate requests AFAIK, but which
one is passed to the zone parameter is ignored.
Tapestry.findZoneManagerForZone(zoneId).updateFromURL(url)
Do you give us permission to use it in Tapestry itself if the team
approves your code?
absolutely. only glaringly obvious problem is that the context
parameters don't get encoded properly, hopefully someone can rectify
this..
Cool!
Feel free to file a JIRA for your suggestions.
I will do.
I'd be keen to contribute further, but I imagine I don't understand
the big picture well enough yet to be a committer.
Give your suggestions and let the Tapestry team decide. :)
