I sort of already sent this message to the list but I made a mistake (didn't
proof read my message) so here it is again but corrected ...
Validator "required" validation is NOT working for my String[] (in a
dynaform. I have seen others on the list say it works for them.
Anyone else experiencing the same problem? Possibly it is because I am using
a multi-select?
Basically, if nothing is selected then instead of null be sent back for that
parameter I am getting a zero length String[]and it's toString() value is
"[Ljava.lang.String;@3cfaab" which is important because of the way the
validateRequired() method works...
I looked at the source code (of my commons-validator.jar using jad).
Maybe I am using an older version of the commons-validator jar and this was
fixed or I am doing something else wrong?
If so, where is the latest commons-validator.jar?
Here is how my field is declared on the JSP:
<html:select property="roles" multiple="true" size="7">
<html:options collection="<%=my.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[]"/>
----------------------------------------------------------------------------
Struts 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 it is some String like "[Ljava.lang.String;@3cfaab" and so
then isBlankOrNull() is checking for null OR value.trim().length==0 and so
neither is true and so validation passes.
