I have read a question here and it was explained there that view expires exception happens when state is saved to server but I have my state saved to client see my web.xml below. How I achieve this is my progressing into my application and then stopping the server manually and starting again. After that I hit any command button and I get my ViewExpired Exception.
Is this correct behaviour ? I understand that restarting of server will be destroying my session but if state is saved on client( browser ) then I should not it be able to get the state ?
web.xml
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
