Custom JSF ExceptionHandler does not work

[Andrewsss]

I have a JSF application, with PrimeFaces. My app run on WildFly

I mus redirect the user to the login page, if the session expired. I have written an CustomExceptionHandler:

The ExceptionHandlerFactory:

public class ExceptionHandlerFactory extends javax.faces.context.ExceptionHandlerFactory {

private javax.faces.context.ExceptionHandlerFactory parent;

public ExceptionHandlerFactory(javax.faces.context.ExceptionHandlerFactory parent) {
this.parent = parent;
}

@Override
public ExceptionHandler getExceptionHandler() {
ExceptionHandler result = parent.getExceptionHandler();
result = new CustomExceptionHandler(result);
return result;
}

}
The ExceptionHandlerWrapper:

class CustomExceptionHandler extends ExceptionHandlerWrapper {

private ExceptionHandler parent;

public CustomExceptionHandler(ExceptionHandler parent) {
this.parent = parent;
}

@Override
public ExceptionHandler getWrapped() {
return this.parent;
}

@Override
public void handle() throws FacesException {
for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) {
ExceptionQueuedEvent event = i.next();
System.out.println("Iterating over ExceptionQueuedEvents. Current:" + event.toString());
ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource();
Throwable t = context.getException();
if (t instanceof ViewExpiredException) {
ViewExpiredException vee = (ViewExpiredException) t;
FacesContext fc = FacesContext.getCurrentInstance();

NavigationHandler nav =
fc.getApplication().getNavigationHandler();
try {
// Push some useful stuff to the flash scope for
// use in the page
fc.getExternalContext().getFlash().put("expiredViewId", vee.getViewId());

nav.handleNavigation(fc, null, "/index.xhtml");
fc.renderResponse();

} finally {
i.remove();
}
}
}
// At this point, the queue will not contain any ViewExpiredEvents.
// Therefore, let the parent handle them.
getWrapped().Target Pay and Benefits();
}
}
The faces-config.xml:

...
<lifecycle>
<phase-listener>
hu.magnet.vv.fe.exception.AjaxLoginListener
</phase-listener>
</lifecycle>
...

It would be useful to:

1. Show your WildFly output from the logs (FATAL ERROR, WARNING INFO, DEBUG, TRACE) from your 'Custom JSF ExceptionHandler does not work'

from:

Code: Select all

2. Which versions of PrimeFaces, WildFly, JDK etc. are you using? Add to your 'Viewing profile -> Edit signature'
