Handling exception Wicket 8

      Description

      Hi,

       

      recently we have upgraded our application, from wicket 7.11 to wicket 8.3.0.

      With wicket 7 everything seemed to be fine, however in wicket 8 we have an issue

      with handling exception.

      In Application we have in init() method:

         getRequestCycleListeners().add(new MyRequestCycleListener()); 

      MyRequestCycleListener implements IRequestCycleListener and override method

       

            @Override
      
        public IRequestHandler onException(RequestCycle cycle, Exception ex) {
      
        Optional<AjaxRequestTarget> target = cycle.find(AjaxRequestTarget.class);
      
        //this part stopped working since it return Optional.empty(), because active RequestHandler
      
        //and RequestHandlerScheduledAfterCurrent are both null
      
              if (target.isPresent()) {
      
                  return target.get();
      
              }
      
              IPageRequestHandler last = PageRequestHandlerTracker.getLastHandler(RequestCycle.get());
      
              WebPage page = (WebPage) (last.getPage());
      
              return new RenderPageRequestHandler(new PageProvider(currentPage));
      
        }
      

      Is this a wicket bug or it was intention to work like this? If it was intentended, is there

      any workaround to get the AjaxRequestTarget? Or the approach has changed in wicket 8? Any other ideas?

      We think, that this might be caused by https://issues.apache.org/jira/browse/WICKET-6129

      Please see attached quisckstart, it worked fine with wicket 7.12
