Igor, thanks a lot for this hint! With it, I found a solution.
For others with similar problems: I create the following resource in
onBeginRender():
resource = new WebResource()
{
@Override
public IResourceStream getResourceStream()
{
IModel<Collection<T>> model = (IModel<Collection<T>>)
getDefaultModel();
Collection<T> collection = model.getObject();
final String json = generateJson(collection.iterator());
return new StringResourceStream(json, "text/x-json");
}
};
resource.setCacheable(false);
urlConstructor = RequestCycle.get().urlFor(MyPanel.this,
IResourceListener.INTERFACE); // (*)
(You cannot do this in the constructor, as it turns out, because
urlFor() calls
getPage() and this is not a good thing in the constructor -- the
component does
not have a page yet at this stage.)
In addition, I made my component implement IResourceListener with
public void onResourceRequested()
{
resource.onResourceRequested();
}
In this way, a request for the URL (*) will trigger the resource's
onResourceRequested() which in turn outputs the JSON for my JavaScript
component on the browser.

see how Link does it, but essentially you call urlfor(component,

How can I register a resource reference (or, what I actually want:

the

To rephrase my question and hopefully make it clearer: How can I
get a URL
for my component which outputs the current value of my component's
model
(in JSON, XML, or whatever)?
Any ideas?
I know this has come up before,

but I could not find any answer...
Thanks,
Kaspar
