Validator for checkbox

[Stephen Ting <st...@shinyang.com.my>]

i have problems to use validator framework to validate checkbox.
 
I declare an array of string in my DynaValidatorForm, it will hold value
return from a multibox. 
 
i try with the following configuration, but it doesn't work. 
 
even i also try add indexedListProperty="selectedSite" attribute in the
field element and it doesn't work too.
 
could anyone point where i get wrong???
 
 
 
<form-bean name="InventoryEnquiryForm"
               dynamic="true" 
               type="org.apache.struts.validator.DynaValidatorForm">
       <form-property name="itemNo" type="java.lang.String"/>
       <form-property name="description" type="java.lang.String"/>  
       <form-property name="selectedSite" type="java.lang.String[]"/>
       <form-property name="searchLogic" type="java.lang.String"/>

       <form-property name="view"
type="my.com.shinyang.einout.inventory.view.InventoryEnquiryViews"/>

</form-bean>
