Create a processing thread, and dispatch it. Have the thread update
some progress object that you can get access to, and query that
progress with a label (or something more fancy like a progress bar).
Something like:
Link() {
onclick() { create thread, start it }
}
add(new Label("progress", new Model() { getObject() { ... get thread,
return progress }));
label.add(new AjaxSelfUpdatingBehavior(Duration.ONE_SECOND));
Note that you don't want to serialize the thread itself, or the
progress object. You'll have to dynamically retrieve it
(de/serialization will detach the objects).
