I am using JSF 2.0 and Richfaces 4.2 where our application is running in WAS8.0 server. We recently migrated form JSF 1.2 to JSF 2.0. We have got an issue where UI[User Interface] automatically disabled if the user dont do any operation in the UI, later any button clicks or any othe action will not work until we refresh the page.
What could cause this issue? How should i resolve this?
