Spring 3 Collection Binding

Question

How I can bind a collection to a form for inputdata (not for show)

Answer 1

e.g. for a Set<Jokers>

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {
    binder.registerCustomEditor(
        Set.class,
        "[nameOfTheClassMemberItShouldGoto]",
        new CustomCollectionEditor(Set.class) {
            protected Object convertElement(Object element) {
                return (element == null ? null : getQueryService().getJoker(element.toString()));
            }
        }
    );
}

or similar to this
