Firstly I'd ask what is wrong with using session scope - has load testing your applcation shown that session scope is too memory intensive?
It looks like the 'years' list was stored in the form bean. You will need to recreate all of your lists etc (e.g. years) in every action if you are going to move to request scope (or take 'years' out of the form and put it in a session scoped attribute).
