"With an ASO, the value is automatically stored outside the page; with the default storage strategy, it is stored in the session. " Unless you've built a different ASO storage strategy, your value is going into the session and a session timeout will lose that value as well. My advice, build your app defensively. Don't depend on objects being available if they are being pulled from the session, or even the database for that matter. Understand what it means if a session times out at every step of your workflow so you can do the right thing when the object isn't there. Build tests that hit those pages with no session to verify the behavior. Good luck!
