Is there any way to get the same session time out modal popup on the conversational scoped screen or redirect it to the login page ? I also added this to the web.xml but does not work

<error-page>
<exception-type>org.jboss.weld.context.NonexistentConversationException</exception-type>
<location>/login.jsf</location>
</error-page>

Thanks in advance

basically, we're trying to make it possible for users to open multiple tabs in the browser independently each other and manage independent session so that one tab's session expired or crashed for some reason, the other tab should not affected. To do this I ended up with conversational scope and it works independently on the conversational scoped screen but when session timed out from one tab, the other tab timed out also because they are session scoped.
