Theres nothing in the "standard" mask validation that ships with struts that
allows you to do this, but it would be pretty straight forward to write and
configure your own validator to do this. Set up a static mehtod somewhere
that does pretty much what the FieldChecks.validateMask() method does,
except modify the "variable" name to something like "mask2"....
public static boolean validateMask(Object bean,
ValidatorAction va, Field field,
ActionMessages errors,
HttpServletRequest request) {
String mask = field.getVarValue("mask2");
String value = null;
if (isString(bean)) {
value = (String) bean;
} else {
value = ValidatorUtils.getValueAsString(bean,
field.getProperty());
}
try {
if (!GenericValidator.isBlankOrNull(value)
&& !GenericValidator.matchRegexp(value, mask)) {
errors.add(
field.getKey(),
Resources.getActionMessage(request, va, field));
return false;
} else {
return true;
}
} catch (Exception e) {
log.error(e.getMessage(), e);
}
return true;
}
Then change the validation-rules.xml to add the second mask validator
<validator name="mask2"
classname="myPackage.MyFieldChecks"
method="validateMask"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest"
depends=""
msg="errors.mask2"/>
Then in your validation.xml, use both the standard mask and your mask2
validator:
<form name="....">
<field property="..." depends="mask, mask">
<var>
<var-name>mask</var-name><var-value>^.......$</var-value>
</var>
<var>
<var-name>mask2</var-name><var-value>^.......$</var-value>
</var>
</field>

Subject: Validation with 2 masks?
I'd like to a property validation against 2 different regular expressions
with 2 different error messages.
This seems like a fairly common use. Is there a best practice for it?
