--------------------------------------------------------------

In regular apps (non-portlet), the messageStoreInterceptor  just grabs the info 
and puts it in the session, which works, I think the problem you are having is 
that in a portlet environment the session works differently, I can't really say 
for sure as I have never used portlets. I will comment on the email thread and 
close this ticket for now.

>          Issue Type: Bug
>          Components: Plugin - Portlet
>    Affects Versions: 2.1.6
>         Environment: JBoss Portal 2.7.1

> It seems we're correctly directed back to the input when Validation isn't 
> passed, but we cannot pick up the error messages using the usual tags:
> <s:actionerror />
> <s:fielderror />
> We're utilising the portletDefaultStack and our Portlet package is extending 
> struts-portlet-default. Our package has no name-space set.
> For example this is the view, which is the input of the edit action:
>                                <action name="ItemView" 
> class="com.msp.portlets.ItemAction">
>                                                 <interceptor-ref 
> name="portletDefaultStack"/>                                                  
>                                             
>                                                 
> <result>/WEB-INF/jsp/welcome/admin/item.jsp</result>
>                                 </action>            
> This is the edit action:
>                                <action name="ItemEdit" 
> class="com.msp.portlets. ItemAction" method="itemEdit">
>                                                 <interceptor-ref

> name="actionName">ItemView</param>

>                                                 </result>
>                                                 <result type="redirectAction" 
> name="input"> 
>                                                                 <param 
> name="actionName"> ItemView </param>
>                                                  </result>
>                                 </action>
> This works perfectly if the redirectAction input is replaced with a standard 
> JSP forward, and the validation errors are shown to the user.
> Utilising validation XML instead of annotations produces the same problem - 
> redirectAction does not work, JSP does.
> Utilising the messageStoreInterceptor does not help.
