      public class PortletActionRedirectResult
      extends PortletResult

  Portlet modification of the `ServletActionRedirectResult`. This result uses the `ActionMapper` provided by the `ActionMapperFactory` to instruct the render phase to invoke the specified action and (optional) namespace. This is better than the `PortletResult` because it does not require you to encode the URL patterns processed by the `ActionMapper` in to your struts.xml configuration files. This means you can change your URL patterns at any point and your application will still work. It is strongly recommended that if you are redirecting to another action, you use this result rather than the standard redirect result. See examples below for an example of how request parameters could be passed in. This result type takes the following parameters:
  - actionName (default) - the name of the action that will be redirect to
  - namespace - used to determine which namespace the action is in that we're redirecting to . If namespace is null, this defaults to the current namespace
  Example:

       <!-- START SNIPPET: example -->
        <package name="public" extends="struts-default">
            <action name="login" class="...">
                <!-- Redirect to another namespace -->
                <result type="redirect-action">
                    <param name="actionName">dashboard</param>
                    <param name="namespace">/secure</param>
                </result>
            </action>
        </package>

        <package name="secure" extends="struts-default" namespace="/secure">
            <-- Redirect to an action in the same namespace -->
            <action name="dashboard" class="...">
                <result>dashboard.jsp</result>
                <result name="error" type="redirect-action">error</result>
            </action>

            <action name="error" class="...">
                <result>error.jsp</result>
            </action>
        </package>

        <package name="passingRequestParameters" extends="struts-default" namespace="/passingRequestParameters">
           <-- Pass parameters (reportType, width and height) -->
           <!--
           The redirect-action url generated will be :
           /genReport/generateReport.action?reportType=pie&width=100&height=100
           -->
           <action name="gatherReportInfo" class="...">
              <result name="showReportResult" type="redirect-action">
                 <param name="actionName">generateReport</param>
                 <param name="namespace">/genReport</param>
                 <param name="reportType">pie</param>
                 <param name="width">100</param>
                 <param name="height">100</param>
              </result>
           </action>
        </package>
