Exactly.
My Page.do has as a parameter the jsp page along with its Form Bean.
So it will get overwritten.
Now what is the best clearest way to get this done?
Must I absolutely use a Session Bean to maintain the List and the Form
Bean for the user inputted data?

It shouldn't... unless you are overwriting those fields in page.do
explicitly.
Basically what's happening is right after the user hits submit, struts
creates a form bean ( or uses an existing one), fills it from the form,
then validates it. At that point, if there is a problem it forwards to
the input param, without changing the form bean. In the case of the
action, it doesn't even know when or where the form bean was created. It
just does it's thing quite merrily, then hands of to your code.
