validwhen question, help needed

[Andrey Grishin]

Good morning/day/evening, All!
I use Struts 1.2.6 and Tomcat 4.1.29

I have a working email validator for my form:
         <field property="email" depends="email">
            <arg0 key="customer._email"/>
         </field>

I want to use validwhen validator, so I changed the validation to:
         <field property="email" depends="email,validwhen">
            <arg0 key="customer._email"/>
             <var>
                <var-name>test</var-name>
                <var-value>CONDITION HERE</var-value>
             </var>
         </field>
But nothing happens whatever condition I place. Even if I place something 
obviously wrong, like "sdf OR SDFs12".
Really nothing. No exceptions in the log, generated html remains the same. 
Have I missed something?

Any ideas will be appreciated.

Regards, Andrey Grishin.
