You get IllegalArgument exception if any of the objects in the path model.currentPerson.contactInfo.emails[0].emailAddress are not instantiated and the stack trace also should able to give you which property is null. Its thrown by BeanUtils when trying to set the property. The action that displays the JSP usually instantiates com.mycomp.SecurityAdminModel object or retrieves from business or data layer to intialise the dynaform. The form bean needs to be session scope, so that the objects currentPerson,contactInfo,emails[0] etc are not null when the form is submitted and no indexed setter and getter methods are required. Your Collection of emails should be a ordered collection like a List.
