JSF Ajax Navigation timeout

Question

I'm using a selectonemenu combined with ajax to navigate.

JSF code

<p:selectOneMenu value="#{navigator.outcome}">                      
    <f:selectItem itemLabel="Select page..." />
    <f:selectItem itemValue="page1" itemLabel="Page 1" />
    <f:selectItem itemValue="page2" itemLabel="Page 2" />
    <f:selectItem itemValue="page3" itemLabel="Page 3" />
    <p:ajax event="change" listener="#{navigator.navigate}" />
</p:selectOneMenu>

Managed bean:

public void navigate() {
    FacesContext context = FacesContext.getCurrentInstance();
     NavigationHandler navigationHandler = context.getApplication()
            .getNavigationHandler();

    navigationHandler.handleNavigation(context, null, outcome
            + "?faces-redirect=true");
}

I have an issue where if I leave the page open for a very long time (maybe a few hours) the ajax navigation seems to stop working. Is there some kind of timeout?

It's session timeout. And it's not only ajax requests, every type of requests becomes invalid until you re-access to the page. — Luiggi Mendoza, Feb 25 '13 at 23:09
How do you cope with this? Will form submit not work either? — DD., Feb 26 '13 at 10:52
This problem will go if you use the approach as proposed in this answer on your previous question: http://stackoverflow.com/questions/15008487/jsf-selectonemenu-navigation — BalusC, Feb 26 '13 at 11:52
I couldn't use that as I need it to render properly in the iphone using the native — DD., Feb 26 '13 at 15:33
@BalusC does the timeout issue only happen with Ajax? If I have a submit button will that work? — DD., Feb 27 '13 at 00:14
No, you're basically getting a `ViewExpiredException`, but not dealing with it in any way in case of ajax requests.

Instead of using ajax navigation use the following:

<p:selectOneMenu value="#{navigator.outcome}" onchange="window.location =this.options[this.selectedIndex].value">                      
    <f:selectItem itemLabel="Select page..." />
    <f:selectItem itemValue="page1" itemLabel="Page 1" />
    <f:selectItem itemValue="page2" itemLabel="Page 2" />
    <f:selectItem itemValue="page3" itemLabel="Page 3" />

</p:selectOneMenu>

This works even if the session times out.
