I have used Vaadin 7.5 in the Production. For a session timeout i have declared 120 seconds in web.xml.
The scenario i have opened the 4 tabs and i am working on the current tab as well.After 120 seconds the other three tabs are getting loggedout automatically (Those 3 tabs not used for the mentioned timeout ) and the one which i am concurrently working tab session also getting logged out.
I have logged in using user ‘A’ for first tab and i have opened other few tabs also logged with the same user ‘A’.
I am actively using first tab for continoulsy , if other tabs get session timed out due to inactive for the specified hour,
In this case the first tab which is actively running one also getting loggedout.
