Ok, I've fixed this in CVS... It now uses the ValueStack

I already posted this issue. The problem is that the validation framework uses the properties ONLY from the action, not from the value stack.

So if you want the validation framework works, you have to change you validation file as follows :

<field name="model.userName">
        <field-validator type="requiredstring">
            <message>You must enter a value for username</message>
        </field-validator> 
</field>

BUT it's not a workaround at all, because in your forms, input names are not "model.userName" but "userName", so you can not match directly the FieldError from your input field.
Just to say : it's a bug. If you want model driven validation works, the validation framework must refer to the ValueStack not directly to the action.

Cheers.

Richard.

I am having a problem with getting model driven validation.  I am getting an OGNL exception stating that if can't get the value of my property as defined in the <ActionClassname>-validation.xml file.  I remember reading about a bug in with this and model driven beans but not sure if it is related.   Below is a segment of the excpetion

Sep 30, 2003 2:23:50 PM com.opensymphony.xwork.validator.validators.ValidatorSupport getFieldValue
SEVERE: Caught exception while getting value for field userName
ognl.NoSuchPropertyException: userName
        at ognl.ObjectPropertyAccessor.getProperty(ObjectPropertyAccessor.java:123)
        at ognl.OgnlRuntime.getProperty(OgnlRuntime.java:1219)
        at ognl.ASTProperty.getValueBody(ASTProperty.java:108)
        at ognl.SimpleNode.getValue(SimpleNode.java:129)
        at ognl.Ognl.getValue(Ognl.java:335)
        at ognl.Ognl.getValue(Ognl.java:310)
        at com.opensymphony.xwork.validator.validators.ValidatorSupport.getFieldValue(ValidatorSupport.java:80)
        at com.opensymphony.xwork.validator.validators.RequiredStringValidator.validate(RequiredStringValidator.java:23)

Here is a segment of the validation.xml file

<field name="userName">
        <field-validator type="requiredstring">
            <message>You must enter a value for username</message>
        </field-validator>
    </field>

And I my model does have a getter and setter with the correct case.

And lastly here are there interceptors and the order of which they are called.
                <interceptor-ref name="defaultStack"/>
            <interceptor-ref name="component"/>
            <interceptor-ref name="model-driven"/>       
            <interceptor-ref name="validation"/>
            <interceptor-ref name="workflow"/> 

Any help?
