JSF Session timeout NPE instead ViewExpiredException - nullpointerexception

Question

JSF(jboss - 2.2.6), AS Wildfly 8.1.0, Deltaspike 1.0.3
After the session has expired, is pressed button (ajax call). The problem is that is thrown a NullPointerExceptiion instead of ViewExpiredException.
There is an ExceptionHandlerWrraper.
public class CoreExceptionHandlerWrapper extends ExceptionHandlerWrapper {
private final BeanManager beanManager;
private final ExceptionHandler wrapped;
public CoreExceptionHandlerWrapper(final ExceptionHandler wrapped) {
this.wrapped = wrapped;
this.beanManager = BeanManagerProvider.getInstance().getBeanManager();
}
#Override
public ExceptionHandler getWrapped() {
return this.wrapped;
}
#Override
public void handle() throws FacesException {
FacesContext context = FacesContext.getCurrentInstance();
Iterator<ExceptionQueuedEvent> it = getUnhandledExceptionQueuedEvents().iterator();
while (it.hasNext()) {
try {
ExceptionQueuedEvent evt = it.next();
ExceptionToCatchEvent etce = null;
if (context == null || !context.getPartialViewContext().isAjaxRequest()) {
etce = new ExceptionToCatchEvent(evt.getContext().getException(), WebRequestLiteral.INSTANCE);
} else {
etce = new ExceptionToCatchEvent(evt.getContext().getException(), FacesRequestLiteral.INSTANCE);
}
beanManager.fireEvent(etce);
} finally {
it.remove();
}
}
getWrapped().handle();
}
}
The FacesException is handled by:
void showFacesMessage(#Handles #FacesRequest ExceptionEvent<Throwable> evt, FacesContext fc) {
Throwable exception = evt.getException();
persistException(evt.getException());
if(exception instanceof ViewExpiredException) {
NavigationHandler nav = fc.getApplication().getNavigationHandler();
try {
nav.handleNavigation(fc, null, "/login.xhtml?faces-redirect=true");//?faces-redirect=true&exceptionMessage=" + exceptionMessage
} catch(Exception e) {System.out.println(e.toString());}
fc.renderResponse();
}

Answer 1

After debugging I was able to find the main problem of NullPointerException. There are components in the view using binding attribute referencing javax.faces.component.UIInput objects in the bean(javax.faces.view.ViewScoped). When the session expires and ajax call is maded and creates (two times) a new instance of the bean. I don't why UIInput force creation of the bean, but this is another topic. In the method annotated with #PostConstruct has a code that throws the NullPointerException. If this exception is handled properly after that is thrown the expected ViewExpiredException.
