If you want to ensure that at least one item is selected from the
mulit-select list you can use "required" just like with the drop-down.
If you need something more (like at least 2 items selected), to use
Validator you will need to create a custom rule.

Hi,
I have a JSP Page where I have a multiple selection Listbox. When the
user submits the page, there should be some values in this listbox. How
do I make the validations for the same in validator.xml ?
I have done similar thing for dropdown by the following entry in
validator.xml
<field property="reportType" depends="required ">
<arg0 key="prompt.reportType"/>
</field>
How can I achieve the similar thing for Multi Select ListBox ?
TIA,
Priya
