Description

I'd like to throw e.g. NotLoggedInException which will be handled by onException which then does a RestartResponseAtInterceptPage:

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);
		}
	}
}

which doesn't work:

because Wicket requires an IRequestHandler instead in this phase.
