this sure seems familiar. didn't we have a nice plan to address this a few
months back?

Overriding the onRuntimeException does not work because you don't have
access
to the page that you are directing to. The page parameter in this method
if
the context from where the exception was thrown.

Re: [Wicket-user] Exception Strategy in 1.3
You can return the page you want to be displayed and have full
control. I know the API currently is non-obvious; I complained about
this in another thread.
For example, this is what I'm using for the project I'm working on:
public Page onRuntimeException(Page page, RuntimeException e) {
if (e instanceof AuthorizationException) {
return super.onRuntimeException(page, e);
} else if (e instanceof PageExpiredException) {
Ts4Session session = Ts4Session.get();
if (session.isTemporary() || session.getUserId() ==
null) {
// this was an actual session expiry
log
.info(session expired and
request cannot be honored, cycleId:
+ cycleId);
return super.onRuntimeException(page, e);
} else {
log.error(unable to find page for an active
session!);
// hmmm, we have a logged in user, but the page
could not be
// found. Fall through to display an error page
or exception
// page
}
}
if (Application.DEPLOYMENT.equals(Application.get()
.getConfigurationType())) {
return new ErrorPage(e, page, cycleId);
} else {
return new ExceptionErrorPage(e, page);
}
}
