------------------------------------

             Summary: 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}

{code}

because Wicket requires an {{IRequestHandler}} instead in this phase.
