--------------------------------------
Thank you for the tip :)
> IRequestHandler implementation for RestartResponseAtInterceptPageException
> --------------------------------------------------------------------------
>
> Key: WICKET-5661
> URL: https://issues.apache.org/jira/browse/WICKET-5661
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 6.16.0
> Reporter: Hendy Irawan
> Priority: Minor
>
> I'd like to throw e.g. {{NotLoggedInException}} which will be handled by
> {{onException}} which then does a {{RestartResponseAtInterceptPage}}:
> {code}
> private final class NotLoggedInRequestCycleListener extends
> AbstractRequestCycleListener {
> @Override
> public IRequestHandler onException(RequestCycle cycle, Exception ex) {
> // Since our actual exception is wrapped, we need to find based
> on the chain
> final List<Throwable> chain = Throwables.getCausalChain(ex);
> final NotLoggedInException notLoggedInException =
> Iterables.getFirst(
> Iterables.filter(chain,
> NotLoggedInException.class), null);
> if (notLoggedInException != null) {
> final Url url = cycle.getRequest().getClientUrl();
> log.debug("Got exception " +
> notLoggedInException.getClass().getName() + " on " + url, ex);
> final SoluvasWebSession session = (SoluvasWebSession)
> Session.get();
> session.setOriginalUrl(url);
> session.info("Please log in");
> session.dirty();
> throw new
> RestartResponseAtInterceptPageException(DedicatedLoginPage.class);
> } else {
> return super.onException(cycle, ex);
> }
> }
> }
> {code}
> which doesn't work:
> {code}
> Caused by: javax.servlet.ServletException: Cannot process filter:

> Caused by: org.apache.wicket.RestartResponseAtInterceptPageException
> {code}
> because Wicket requires an {{IRequestHandler}} instead in this phase.
