Validation is working for my String[] dynaform attributes. I have seen
others on the list say it works for them.
So I looked at the source code (of my commons-validator.jar using jad).
Either it can't be working or I am using
the wrong version of that jar. Do I need to get the latest
commons-validator.jar? If so, I don't remember where I
retrieved the one I have now. Did it come with Struts download?
Source Code:
public static boolean validateRequired(Object bean,
ValidatorAction va, Field field,
ActionErrors errors,
HttpServletRequest request) {
String value = null;
if (isString(bean)) {
value = (String) bean;
} else {
value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
}
if (GenericValidator.isBlankOrNull(value)) {
errors.add(field.getKey(),
Resources.getActionError(request, va,
field));
return false;
} else {
return true;
}
}
Problem:
ValidatorUtil.getValueAsString(bean, field.getProperty()) does a toString()
on the value and a toString() on a String[]
which isn't null is some String like "[Ljava.lang.String;@3cfaab" and so
then isBlankOrNull() is checking for null or
value.trim().length==0
Here is how my field is declared on the JSP:
<html:select property="roles" multiple="true" size="7">
<html:options
collection="<%=acint21.web.util.Const.ROLE_TYPES%>"
property="roleName" />
</html:select>
Here is how it is declared in the struts config:
<form-property name="roles" type="java.lang.String[]"/>
