Aside from form field definition, which isn't needed for a lazy form bean, having a FormDef-backed form would take care of the formatting/parsing of the data, even i18n. The form definition & validation config combo is actually just optional.
My understanding of the question on the user list was for a form which contained an array of beans, instead of just an array of strings. An example would be a form bean containing a list/array of children, each with a name, date of birth, daily allowance, etc. If each child is a dyna form, I can use FormDef for each element.
