//choices in list box

private static final List<String&GT; NUMBERS = Arrays.asList(new String[] {"Number 1", "Number 2", "Number 3", "Number 4", "Number 5", "Number 6" });

//variable to hold the selected multiple values from listbox,

//and MAKE "Number 6" selected as default VALUE

private ArrayList<String> selectedNumber = new ArrayList<String>(

Arrays.asList(new String[] { "Number 6" }));

ListMultipleChoice<String> listNumbers = new ListMultipleChoice<String>(

"number", new Model(selectedNumber), NUMBERS);

//HTML for multiple select listbox
