Craig and company, I'll comment some more below but I want to first explain what needs to be set up and handled. I have an ArrayList of beans. Each bean in this ArrayList also contains an ArrayList of String object. On my JSP I'm using the nested tag (new to using it- bannana stuff very helpful Arron) to create the dynamically created form. ( Picture a JSP that was to display a dynamic list of cars and for each car there would be list of particular styles you could pick from).

A DTO is populated with the ArrayList of beans and then the DTO is converted to the DynaActionForm which is set into request scope. (The nested tag and display of the information on the page is working beautifully..problem is upon submission). >> What if the information in an ArrayList of beans that you want in a >> DynaActionForm is to first be populated by some database info. >> Do you need to first initialize it like a above to a bunch of >> nulls?

Ok, well what I've done is added this to the base class that my DynaActionForm (actually DynaValidatorForm) extends (Roman on this list was helping me with this) (20 is just an arbitrary number greater than the amount that would be displayed on the form): public class UserDynaForm extends DynaValidatorForm { public void reset( ActionMapping mapping, HttpServletRequest request ) { ArrayList applicationGroups = new ArrayList(); for (int i=0; i < 20; i++) { ApplicationGroupBean b = new ApplicationGroupBean(); b.setRoles( new ArrayList() ); applicationGroups.add(b); } set("applicationGroups", applicationGroups); } } I then still have in my struts-config, for this form: <form-bean name="userForm" dynamic="true" type="corporate.userAdmin.UserDynaForm">: <form-property name="applicationGroups" type="java.util.ArrayList"/> .... The page will display the initial information fine. When I submit now, however, the problem is it's trying to submit nulls. It's as if it doesn't pick up what was selected on the JSP and this reset is wiping out what was selected? I'm sure I'm missing something simple so sorry for my ignorance. I guess what is so odd is that when I switch to using a standard ActionForm I don't have to override the reset and the page submits fine.
