As you write ListChoice are no longer invoked. The ajax event are called afaik
after all updates of model has occurred. I actually changed my coding style
after this and began using abstract models, its actually much easyer coding
this way, and all of your components will be ajax prepaered...:)
Heres a code sniplet of what I do:
dropdown.add(new AjaxFormComponentUpdatingBehavior("onchange") {
public CharSequence getCallbackUrl() {
// hack since url is not encoded and so will
fail xhtml
// validation
String s = getCallbackUrl(true).toString();
return s.replaceAll("&wicket", "&wicket");
}
protected void onUpdate(AjaxRequestTarget target) {
AJAXpopulatepaletteList();
if (submit) {
target.addComponent(paletteSubmit);
if (addit) {
Iterator iter =
additional.iterator();
while (iter.hasNext()) {
target.addComponent((Component) iter.next());
}
}
} else {
target.addComponent(palette);
if (addit) {
Iterator iter =
additional.iterator();
while (iter.hasNext()) {
target.addComponent((Component) iter.next());
}
}
}
}
});

Yes, the examples are good and it is where I started off when I look into
Wicket's AJAX.
I have questions: -
1. ListChoice.onSelectionChanged is not invoke when I add
AjaxFormComponentUpdatingBehavior to ListChoice. Does this mean ListChoice
behavior is handled thru AjaxFormComponentUpdatingBehavior after it is added
to the component?
2. AjaxFormComponentUpdatingBehavior.onEvent is called when there is an AJAX
event. What is AJAX event?
