Flash created in ExceptionHandler not work
------------------------------------------
Key: MYFACES-3358
URL: https://issues.apache.org/jira/browse/MYFACES-3358
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Affects Versions: 2.1.3
Environment: WebSphere 8.0
Reporter: Keith Wong
I have a custom ExceptionHandler for handling ViewExpiredException as occurred
in session timeout or application restart. I have to tell the user in the
redirected page the reason for being redirected. Here is the handler:
public void handle() throws FacesException {
for (Iterator<ExceptionQueuedEvent>
i=getUnhandledExceptionQueuedEvents().iterator(); i.hasNext(); ) {
ExceptionQueuedEventContext context =
i.next().getContext();
Throwable t = context.getException();
if (t instanceof ViewExpiredException) {
FacesContext ctx =
FacesContext.getCurrentInstance();
ViewExpiredException vee =
(ViewExpiredException)t;
try {
ctx.addMessage(null, new
FacesMessage(FacesMessage.SEVERITY_ERROR, vee.getClass().getName(),
vee.getMessage()));
Flash flash =
ctx.getExternalContext().getFlash();
flash.put("expiredViewId",
vee.getViewId());
flash.setKeepMessages(true);
ctx.getApplication().getNavigationHandler().handleNavigation(ctx, null,
"/login?faces-redirect=true");
ctx.renderResponse();
}
finally {
i.remove();
}
}
}
super.handle();
}
In the login.xhtml, it has #{flash.expiredViewId} and <f:messages> but both are
empty when displayed.
