Oh yeah....You're not meant to call renderResponse() on
ResponseBuilder yourself, that's mostly reserved for internals - but
since I do have a nice public/internal API structure like T5 I have to
expose it to everyone else..
I'm not sure I understand completely, but this could be made much
simpler by doing something like implementing IJSONRender....The
rendering method for that interface will ~only~ be called during json
requests so you don't have to worry about when which method gets
called....
The Autocompleter component does a direct listener callback with json
response as well, so it may be perfect as an example.

Hi Jesse,
i just want do call the Dojo DojoAjaxResponseBuilder to return a "OK"
string. But i dont know how to do this from within my component. Anytime i
obtain the ResponseBuilder from the cycle and call renderResponse i get
a exception. i know i'm missing something but i didn't figure out what....
:)
My component looks sth like this
component:
public abstract class AsyncListenerCaller extends AbstractComponent
implements IDirect {
@InjectScript("AsyncListenerCaller.script")
public abstract IScript getScript();
@InjectObject("infrastructure:listenerInvoker")
public abstract ListenerInvoker getListenerInvoker();
@InjectObject("service:tapestry.services.Direct")
public abstract IEngineService getEngine();
protected void renderComponent(IMarkupWriter writer, IRequestCycle cycle) {
renderBody(writer, cycle);
HashMap<String,Object> scriptParameters = new HashMap<String,Object>(2);
scriptParameters.put("href",getLink(cycle).getURL());
scriptParameters.put("jsFunctionSuffix", getJsFunctionSuffix());
// for rendering scripts
PageRenderSupport pageRenderSupport =
TapestryUtils.getPageRenderSupport(cycle, this);
// render script
getScript().execute(this, cycle, pageRenderSupport, scriptParameters);
}
public ILink getLink(IRequestCycle cycle) { // creates a ILink
DirectServiceParameter dsp = new DirectServiceParameter(this, new
Object[] {});
return getEngine().getLink(false, dsp);
}
public void trigger(IRequestCycle cycle) {
getListenerInvoker().invokeListener(getListener(), this, cycle);
}
script:
<unique>
dojo.require("tapestry.event");
</unique>
function asyncListener${jsFunctionSuffix}(data) {
tapestry.bind("${href}", data, false);
}

Don't specify which components to update? Or make it a json render and
return some meta protocol between your client and server?
