JSF page fails to reflect saved changes to model

Question

How do I refresh the info kept in the JSF backing bean in order to reflect changes saved to the model?
My JSF page contains rows of data. Depending on the user’s choices, one or more rows may be eliminated from the model. My problem is the change in the model is never reflected in subsequent page displays, unless I kill the session. I’m sure this behavior is because the backing bean has a scope of session and the data loaded into the session bean never changes to reflect the change in the model. Invalidating the session kills everything including stuff I want to keep around (like logon info and other stuff that will really never change during the session). Changing the backing bean scope to request breaks the update completely.
Help!!!

Thanks for the reply.
I have (actually had) two problems. The first one I've solved since my initial post (stupid error on my part).
The other unsolved problem is JSF pages displaying stale data. User navigates to first page, navigates to second page, at this point the database changes, and then the user navigates back to first page. Navigating back to the first page shows the data how it was, not how it is, because it's from the session bean and not the database. If I could kill the session bean when the user navigates from the page the problem would be solved because I build the inital display in the constructor (BTW, please advise if this is a bad approach).
Frank, your reply raised a question. Is there a way to specify a refresh frequency? If so, how?
