Try to do without it first, and when there are specific things you
can't do, ask a question here. Components and resources should take
care of their own cleanup etc. You don't need to directly get
parameters from the request. Rather then the code that you provide,
with Wicket you would do e.g. (Wicket 2.0 code):
class ActionLink extends Link {
private final String action;
@SpringBean ComponentManager componentManager;
public ActionLink(MarkupContainer parent, String id, String action) {
super(parent, id);
this.action = action;
}
public void onClick() {
componentManager.getAction(action).execute();
}
}
And in fact I'm wondering what that component manager is doing anyway?
As this would be more typical:
final String someBar ...
new Link(this, "doFoo") {
public void onClick() {
fooHandler.doFoo(someBar);
}
}

no, it's more like:
protected IRequestCycleFactory getRequestCycleFactory() {
return new IRequestCycleFactory() {
public RequestCycle newRequestCycle(
Session session, Request request, Response response) {
return new CountingRequestCycle((WebSession)session,
(WebRequest)request,
(WebResponse)response);
};
}
public class CountingRequestCycle extends WebRequestCycle {
public CountingRequestCycle(WebSession session,
WebRequest request, Response response) {
super(session, request, response);
}
protected void onBeginRequest() {
((CountingWebSession) getSession()).hit();
}
}
etc.
