I want to validate that the lists value of my form arent 0
this is the validation method in my FMValidation class
public static boolean validateList(
Object bean,
ValidatorAction va,
Field field,
ActionErrors errors,
HttpServletRequest request) {
String value = ValidatorUtils.getValueAsString(bean,
field.getProperty());
System.out.println("VALOR:["+value+"]");
if (!GenericValidator.isBlankOrNull(value)) {
try {
if (value.equalsIgnoreCase("0")) {
System.out.println("VALOR 0");
errors.add(field.getKey(),
Resources.getActionMessage(request, va, field));
return false;
}
} catch (Exception e) {
errors.add(field.getKey(),
Resources.getActionMessage(request, va, field));
return false;
}
}
return true;
}
the validation rules is this
<!-- VALIDADOR DE LOS VALORES DE LAS LISTAS-->
<validator name="listas"
classname="validator.FMValidator"
method="validateList"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
depends=""
msg="errors.list"/>
and my validation is the following (NOTE: the list name Im validating

<field property="escuela" depends="listas">
<arg0 key="escuela"/>
</field>
