You might want to use

 
    javax.faces.application.ViewExpiredException
    /sessionExpired.jsf

in you faces-config.xml it might work for you. There is also a way of defining on how to catch errors in web.xml

Thanks for the solution. But I still do have some problems getting around my basic issue.
I have a secured application (Spring security), with a simple login form. I can happen fairly often that the user opens the login page and leaves the browser open without performing a login.
The session times out and when the user tries to login he would get a ViewExpiredException.
Displaying a session-time-out-page makes no sense, the user was at the start page and overriding the ViewExpiredException-behaviour for this single, simple issue seems like a dangerous overkill for me.
Is there any other way telling JSF this is the start page, we do not need a stored view for this??? I have read numerous articles about this and it has been bugging me for nearly a year(!) that you need to make fairly big changes in the JSF-ecosystem for imho a very, very common problem.
Where am I wrong?

If you’re using Facelets you can extend FaceletViewHandler and just have the restoreView() method. In my case I also return an error/information page if root == null. I think it’s more user friendly. Here’s the code:

public class MyFaceletViewHandler extends FaceletViewHandler {
 
    public MyFaceletViewHandler(ViewHandler parent) {
        super(parent);
    }
 
    @Override
    public UIViewRoot restoreView(FacesContext facesContext, String viewId) {
        UIViewRoot root = super.restoreView(facesContext, viewId);
        // do not allow ViewExpiredException
        if (root == null) {
            root = createView(facesContext, "/viewExpired.xhtml");
            facesContext.renderResponse();
        }
        return root;
    }
 
}

Comment on TabWidget demo project by Greg

There are couple different ways of doing it.
Personally I like to download the source for tabwidget then reference that project from
project where I will be using the tabs. ON TabWidget Source project you will need to edit ‘.proect’ file and disable few features.
