Hi,

I have defined and created a custom validator on an HtmlPickList, but the
problem is that the validator gets called only if there has been interaction with the picklist (eg: item selected)

<rich:pickList id="usersPickList"
 value="#{selectUsersModuleBean.targetUsers}"
 showButtonsLabel="false"
 converter="UserConverter"
 rendered="false">
 <f:validator validatorId="RecipientsValidator" />
 <f:selectItems value="#{selectUsersModuleBean.users}" />
 </rich:pickList>

public class RecipientsValidator implements Validator {

 @Override
 public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
 if ((context == null) || (component == null)) {
 throw new IllegalArgumentException(context == null ? "Context" : "Component" + " cannot be null");
 }

 List recipients = (List)value;
 if (recipients.size() < 1) {
 throw new ValidatorException(new FacesMessage("'Recipients' is required"));
 }
 }

}
