DynaValidatorForm and Struts validator - not working at all...

[Jacek The Java Newbie]

I defined a simple DynaValidatorForm:

<form-bean name="personnelSearchForm" 
            type="org.apache.struts.validator.DynaValidatorForm">
            <form-property name="personnelID" type="java.lang.Integer"/>
            <form-property name="firstName" type="java.lang.String"/>
            <form-property name="lastName" type="java.lang.String"/>
 </form-bean>

Have an action that uses it:

 
<action input="/WEB-INF/pages/admin/personnelSearch.jsp" 
            name="personnelSearchForm" 
            path="/modules/admin/personnelSearchAction" 
            scope="request" 
            validate="true"
            type="com.ris.struts.admin.PersonnelSearchAction">
            <forward name="success" path="admin.personnelEdit" />
            <forward name="failure" path="admin.personnelSearch"/>
</action>
 

Set up validation.xml to make "personnelID" an integer:

<form name="personnelSearchForm">
            <field property="personnelID" depends="integer">
                <arg key="field.personnelID"/>
            </field>
</form>

Properly hooked up the Javascript in the JSP:

<html:javascript formName="personnelSearchForm"/>
 
<html:form action="/modules/admin/personnelSearchAction" 
    onsubmit="return validatePersonnelSearchForm(this);">
    <table class="form">
        <tr>
            <td><bean:message key="field.personnelID"/>:</td>
            <td><html:text property="personnelID" styleClass="text"/></td>
        </tr>
        <tr>
            <td><bean:message key="field.firstName"/>:</td>
            <td><html:text property="firstName" styleClass="text"/></td>
        </tr>
        <tr>
            <td><bean:message key="field.lastName"/>:</td>
            <td><html:text property="lastName" styleClass="text"/></td>
        </tr>
    </table>
    <html:submit titleKey="button.search" styleClass="submit">
        <bean:message key="button.search"/>    
    </html:submit>
</html:form>
 
<html:errors/>

The client-side Javascript validation works perfectly. No issue there. But, if I disable Javascript in IE and try to test the server-side valdidation, nothing happens. It happily gets to my Action even though I have entered a non-integer value into the PersonnelID field.

Help! I am losing my mind trying to figure out where is the problem in the myriad of Struts XML files.

P.S. I am using Netbeans 5.0, using its Struts support. So the web.xml and validation-rules.xml are all configured and set up properly (I believe).
