If you make sure your models/ components work lazily you can avoid database calls being done until the components are actually rendered. Rendering is a separate phase executing after component construction and form handling. And you can let your form just populate a simple bean to avoid database access. I wouldn't worry about the creation of a few components, and you can break of any time with a RestartResponseException or set the next page (without breaking off current processing) using setResponsePage.
