I didn't find in the documentation any reference on how I can deal with session expiration. For example if I edit a cell in a grid and the session is expired, I get an error. What I would like to happen is to display some kind of message popup and redirect the user to some specific page (usually the login page). Any ideas on how I can do that?
This is related to application server that you are using, and it is not covered by our support team.
The only mechanism we have is to reload the page when the session expire during an AJAX request.
A suggestion would be to use a phase listener in JSF or a servlet filter where you can detect if session expired based on some flag set in session map where you can treat the problem.
What is the error you are getting during editing in gridtable?
