>                 Key: WICKET-3001
>                 URL: https://issues.apache.org/jira/browse/WICKET-3001
>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 1.5-M1
>            Reporter: Daniel Soneira

> Code:
> --------------------------
> ...
> new AjaxLink<Void>("link") {
>     @Override
>     public void onClick(AjaxRequestTarget target) {
>         feedback("link clicked");
>     }
> }
> public void feedback(String message) {
>      info(message);
>      AjaxRequestTarget target = AjaxRequestTarget.get();
>      if (target != null) {
>          target.addComponent(get("feedback"));
>      }
> }
> ...
> -------------------------- 
> In previous versions of Wicket this code worked.
> Now target is null and therefore the feedback panel is not re-rendered.
> Debugging AjaxRequestTarget.get shows that the active request handler is a ListenerInterfaceRequestHandler with an AjaxRequestTarget as next "scheduled" handler.
