Description
if validation xml uses message key:
<field name="password">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message key="password.required"/>
</field-validator>
</field>
from property file:
password.required=password is required
and client-side validation is enabled:
<s:form action="doLogin" method="POST" theme="css_xhtml" validate="true">
then property key "password.required" is displayed instead of it value "password is required" when validation fails.
