short-circuit attribute not working in validation file

[MaheshS Kumbhar]

I have following xml validation file. But in this file, short-circuit attribute is not working as it is supposed to be. Even though I fail to enter the name in form field, rest other validators are still getting evaluated which should not evaluate if name validator fails and is short-circuited.
What is the problem in below validation xml file?

<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="name">
<field-validator type = "requiredstring" short-circuit="true">
<message>Name must be entered</message>
</field-validator>
</field>

<validator type="int">
<param name="fieldName">age</param>
<param name="min">18</param>
<param name="max">25</param>
<message>Age must be between ${min} and ${max}</message>
</validator>

<field name="email">
<field-validator type="email">
<message>Not a valid email</message>
</field-validator>
<field-validator type = "requiredstring">
<message>You must enter email</message>
</field-validator>
</field>

</validators>
