Generally you can get the callback-url of a wicket ajax-component with
calling getCallbackUrl(), you should have a look at wicketAjaxGet which is
part of wicket's JS library
to make the whole stuff a bit more dynamic you could make a javascript
template using wicketstuff-dojo, e.g.
function callWicket() {
var wcall = wicketAjaxGet('${url}' + addToUrl, function() { }, function()
{ }); // addToUrl are optional parameters
}
and then in the java-code
HashMap<String, String> map = new HashMap<String, String>();
map.put("url", getCallbackUrl().toString()); // getcallbackurl
is from
AbstractAjaxBehavior
return new DojoPackagedTextTemplate(YourClass.class,
"CometdDefaultBehaviorTemplate.js")
.asString(map);
and then add it in your responseheader (renderHead method) with
response.renderJavaScript(...)
this may be not the easiest method but allows the most flexibility.
hope that helps
