------------------------------------
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.
