Musachy Barroso commented on WW-2987:
-------------------------------------
fieldErrors, actionErrors and actionMessages are lost on redirects. Using the
session(messageStoreInterceptor uses the session) is the way to go, if you need
to do a redirect. There isn't much that struts can do in this case.
> Validation messages do not get displayed using a redirectAction as the input

> Key: WW-2987
> URL: https://issues.apache.org/struts/browse/WW-2987
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Portlet
> Affects Versions: 2.1.6
> Environment: JBoss Portal 2.7.1
> Reporter: Dean Pullen
>
> This was originally posted to the mailing list without being solved.
> 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="portletDefaultStack"/>
>
> <result type="redirectAction"
> name="success">
> <param
> 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.
