Hans, You're using request scope for your form. When Struts processes the submitted form, it will create a new instance of your ActionForm. The question now is, is the new instance ready to deal with setting values on your ArrayList field? Struts will not instantiate that list for you, it wouldn't know how to. So make sure that when Struts accesses your ActionForm, the ArrayList already exists.
