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:
<code>
getRequestCycleListeners().add(new MyRequestCycleListener());
</code>
MyRequestCycleListener implements IRequestCycleListener and override method
<code>
@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));
}
</code>
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?
Matus
