Markus-
You can inject ComponentResources, pass the zoneId and eventlink to
your javascript method with a JSONObject in your javascript
initializer call , and then call the tapestry zone update via client
side javascript.
Example Java Code:
@Inject
private ComponentResources resources;
@Environmental
private JavaScriptSupport javascriptSupport;
@InjectComponent
private Zone yourZone;
void afterRender()
{
Link url = resources.createEventLink("yourMethodName");
JSONObject spec = new JSONObject();
spec.put("zoneId", yourZone.getClientId());
spec.put("url", url.toString());
javascriptSupport.addInitializerCall(InitializationPriority.NORMAL,
"yourJsFunction", spec);
}
Object onYourMethodName()
{
return yourZone.getBody();
}
Example Javascript Code:
Tapestry.Initializer.yourJsFunction = function(spec)
{
....
var zone = Tapestry.findZoneManagerForZone(spec.zoneId);
zone.updateFromURL(spec.url);
....
};
You can also observe the Tapestry.ZONE_UPDATED_EVENT in your
javascript by doing this if you wanted to perform a zone update first
and then do some javascript:
$(spec.zoneId).observe(Tapestry.ZONE_UPDATED_EVENT, someJsFunction)
