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);
}
}
