mask validator error
--------------------
Key: STR-2854
URL: http://issues.apache.org/struts/browse/STR-2854
Project: Struts Action 1
Type: Bug
Components: Core
Versions: 1.2.7
Environment: Windows XP, Weblogic 8.1 SP5
Reporter: Jorge Rodríguez
Priority: Critical
I have a problem with the mask validator when it is used without others
validators such as "required" in struts 1.2.7.
For example, I have a field which depends of a radio button selecction
(requiredif in previous versions). In this case I'm using the "validwhen" and
the "mask" validators because that field is an integer data type, so, i need
to check it. The problem is when it is filled in with only blank spaces. In
this case, the "mask" validator doesn't work.
<field property="txtAnio" depends="mask,validwhen">
<msg name="mask" key="errors.invalid"/>
<arg position="0" key="Año" resource="false"/>
<var>
<var-name>mask</var-name>
<var-value>${numeros}</var-value>
</var>
<var>
<var-name>test</var-name>
<var-value>(((rdSelector==0) and (*this* >0 )) or
(rdSelector==1))</var-value>
</var>
</field>
where:
${numeros} = ^[0-9]*$
rdSelector is my radio button field
txtAnio is a year textfield.
I think, the problem is in the validateMask method of the FieldChecks class
(org.apache.struts.validator):
public static boolean validateMask(Object bean,ValidatorAction va, Field
field,ActionMessages errors, Validator validator, HttpServletRequest request) {
String mask = field.getVarValue("mask");
String value = null;
if (isString(bean)) {
value = (String) bean;
} else {
value = ValidatorUtils.getValueAsString(bean, field.getProperty());
}
try {
if (!GenericValidator.isBlankOrNull(value) // <b>THIS IS THE
PROBLEM</b>
&& !GenericValidator.matchRegexp(value, mask)) {
errors.add(field.getKey(),
Resources.getActionMessage(validator, request, va, field));
return false;
} else {
return true;
}
} catch (Exception e) {
log.error(e.getMessage(), e);
}
return true;
}
The problem I found is in the second if:
if (!GenericValidator.isBlankOrNull(value) && ......
this means that if the field is empty, null or with only blank spaces as the
isBlankOrNull method does,
the field is not considered as invalid (the if block doesn't execute, so no
errors are generated) and the second part of that if never executes because of
the && operator so, the Regular expression is never checked.. so it is almost
right, but fails with blank spaces ..
do you have any options to solve it ?,
Ineed to change the struts.jar ?, I checked the same class in struts 1.2.9 and
the problem remains.
Thanks for your help ..
