How to listen for CHILD ajax form submits
I have a panel. I cannot figure out a way to have this panel informed if any
of its children happens to exectute an AjaxFormSubmittingBehavior form
submit. Ideally, I'd like my panel to listen for this, and have access to
the AjaxRequestTarget. Is there a reasonable way to do this? My panel does
not define the child hierarchy, or where/if there is a form that will be
submitted via ajax from within panel.

Ernesto,
I had thought of that. I was hoping to avoid the custom button/link route,
but seeing as I haven't heard anything more elegant yet, I decided to go
with it for now. Thanks for your input!

If you have full control over the contents of your dialog you could try to
1- create the interface to mark your dialog:
public interface IAjaxSubmitAware {
void onSubmit(AjaxRequestTarget target);
}
2- create your own link, buttons, etc as in
public abstract class MyAjaxSubmitLink extends AjaxSubmitLink {
private static final long serialVersionUID = 1L;
/**
* @param id
*/
public MyAjaxSubmitLink(String id) {
super(id);
}
/**
* @param id
* @param form
*/
public MyAjaxSubmitLink(String id, Form<?> form) {
super(id, form);
}
@Override
protected final void onSubmit(AjaxRequestTarget target, Form<?> form) {
IAjaxSubmitAware submitAware = findParent(IAjaxSubmitAware.class);
if(submitAware != null) {
submitAware.onSubmit(target);
}
doOnSubmit(target, form);
}
protected abstract void doOnSubmit(AjaxRequestTarget target, Form<?> form);
}

if you use 1.5 then you can use the new event mechanism. see WICKET-1312
in 1.4 you can use something like:
new AjaxFormSubmitBehavior("event) {
onSubmit(AjaxRequestTarget target, Form form) {
...
target.addChildren(getPage(), MyDialog.class);
}
}
The last line will register all instances of type MyDialog to be re-rendered
in this Ajax request/response.
Then in your MyDialog#onBeforeRender() { target = AjaxRequestTarget.get();
doSomethingWithTarget(target); }

Anyone? Abstract: I have extended WiQuery Dialog with our own custom
dialog. I want the MyDialog to know if any child components are a Form,
being submitted via AJAX (AjaxFormSubmitBehavior). I need access to the
AjaxRequestTarget created by that ajax form submit so I can append
javascript to it or add components. I'm really hoping someone has a
suggestion that I missed. This is a major blocker for us right now.
