Struts 2 Message Store Interceptor not working with field error (using Hibernate validation)

Question

I have a Jsp with some textfields, these are validate using Hibernate validation annotation (@Valid or @NotNull in the action) except one (input image file) that is validate with default Struts2 validation (using ActionName-validation.xml). I want to redirect to another action when the submitted form is invalid (when textfields are null), and I want to store fields error.

I tried with this:

<interceptors>
    <interceptor name="SessionCheckInterceptor" class="util.SessionCheckInterceptor"/>
        <interceptor-stack name="mySessionValidationStack">              
            <interceptor-ref name="defaultStackHibernate" />
            <interceptor-ref name="SessionCheckInterceptor" />
        </interceptor-stack>      
</interceptors> 

<default-interceptor-ref name="mySessionValidationStack"/> 

<action name="insert" class="actions.InsertAction" >       
    <interceptor-ref name="mySessionValidationStack">
        <param name="fileUpload.allowedTypes">image/png</param>
    </interceptor-ref> 
    <interceptor-ref name="store">
        <param name="operationMode">STORE</param>
    </interceptor-ref>
    <interceptor-ref name="defaultStack" />
    <result name="success" type="tiles" >baseLayout</result>
    <result name="error" type="redirectAction" >
        <param name="actionName">showinsertform</param>
    </result>
    <result name="input" type="redirectAction" >
        <param name="actionName">showinsertform</param>
    </result>
</action>

<action name="showinsertform" class="actions.ShowInsertFormAction" > 
    <interceptor-ref name="mySessionValidationStack" />
    <interceptor-ref name="store">
        <param name="operationMode">RETRIEVE</param>
    </interceptor-ref>
    <result name="success" type="tiles" >insert</result>
    <result name="error" type="tiles" >baseLayout</result>
</action> 

But when I sumbit the form, the redirect succeed without showing me fields error messages. Maybe I'm setting wrong the interceptor? Using hibernate I need to override something? If I try to set manually error messages in the action (with addActionError), they works! Can it be that hibernate error fields messages are not stored in the session?

Hibernate plugin struts-plugin.xml here you are using defaultStackHibernate which is not including store interceptor which is defined in struts-default.xml you should include store interceptor to your custom interceptor stack before using it.
