    Seam Recreating Sessions on Timeout?

    Greg Zoller Newbie

      Hello,

      I'm in the home stretch of my first significant Seam application--Many thanks to all who have helped me out on this forum!

      Everything works great until the user steps away from the session for a few minutes. When they come back the session object is no longer there but Seam is trying to render the requested page. (This is a public page, no login required.)

      The exception is below. It dies when it hits EL in the page that references fields of my session object, which is no longer there. My working theory is that since the original session was timed out Seam is trying to re-create a new session on the fly (true?).

      The ButtonMap referred to in the exception lives in my session object but cannot be dynamically created (it doesn't have a no-param constructor). To successfully create a session and all its contained objects the @Create method needs to be called. Will Seam do that if in fact its trying to re-create the session on the fly or is something else happening?

      Any ideas what's happening and what my options are?

      Thanks,
      Greg
