Listbox Validation in struts

[Priya Jotwani <Pr...@infosys.com>]

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

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.
