Action:

private Date current;

public Date getCurrent(){
    return current;
}

Validator:

<field name="birthday">
    <field-validator type="date">
        <param name="minExpression">01/01/1920</param> 
        <param name="maxExpression">${current}</param> <!--calls getCurrent();-->
        <message>
            <![CDATA[ Your Birth date must be between ${min} and ${max}! ]]>
        </message>             
    </field-validator>
</field>
