Ray Frid,

JSF normally saves the UI component tree state either at Client side or at Server side.

Default Server, in this case UI state stored in session context, so if you were happened to delay your submit request (post back) in such a way session timeout happens then
the UI state stored in it also gone with it.

So you would like to handle this exception and display a proper Session time out page.

Is there any way of preventing this? it happens all the time!

Ofcourse I can handle the exception, and show a proper msg to the user, but isn't it a way of preventing it from first place? or handle it in a way that the page will render itself and work properly?

thanks,

ray,

Try increasing your session timeout in web.xml
