You could do this for your person list, but it'd be a pain because
you'd have to use the <nested:*> tag and write out all your properties
properly. The easier thing to do is look in your XDoclet tags at the
top of your UserAction.java and change request to session.

I am using STruts. In which case, I should put the form in session. What does
that mean? I noticed that in the form there are some hidden inputs like
<form:hidden path="accountExpired"/>
Should I do the same for my personList?
thanks.
