Validation of List property in a Form

[Dhan Raj]

Hi

(1) I am having a form that contains a variable called 'listItem', which is in turn , a variable of type 'java.util.List'.
(2) listItem contains objects of type 'UserInfo'. UserInfo contains two attributes name & city (both Strings)
(3) As part of validation, I have the following
<form name="userInfoForm">
<field property="listItem.name" depends="maxlength,mask" >
<msg name="mask" key="userInfoForm.name.display_msg"/>
<arg0 key="userInfoForm.name.display_name"/>
<var>
<var-name>mask</var-name>
<var-value>^[\w]*$</var-value>
</var>
<arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var>
<var-name>maxlength</var-name>
<var-value>25</var-value>
</var>
</field>

<field property="listItem.city" depends="maxlength,mask" >
<msg name="mask" key="userInfoForm.city.display_msg"/>
<arg0 key="userInfoForm.city.display_name"/>
<var>
<var-name>mask</var-name>
<var-value>^[\w]*$</var-value>
</var>
<arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var>
<var-name>maxlength</var-name>
<var-value>25</var-value>
</var>
</field>
</form>

(4) I have the required setup for displaying errors
(5) The form, 'UserInfoForm' extends 'ValidatorForm'
(6) I have the required setup in struts-config.xml

The problem is struts does not validate the fields even if it is wrong/invalid. How do I fix that? Is there anything that I am missing?
Please HELPPP!

Thanks
