same wish here…

I tried messing up with the faces-config-navigation.xml on the logout action but without success…

Please tell me if you succeed in any way, thanks!

To have the user redirected to the dashboard as the guest user open "tomcat/webapps/alfresco/WEB-INF/faces-config-navigation.xml' and modify the following snippet. Assuming you haven't disabled guest log in it should redirect the user to the dashboard when logging out. This should log in the user as guest as default. Better option is to use the Custom Login sample and modify and package the faces config.

   <navigation-rule>
      <from-view-id>/jsp/*</from-view-id>
      <navigation-case>
         <from-outcome>logout</from-outcome>
         <to-view-id>/jsp/login.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>relogin</from-outcome>
         <to-view-id>/jsp/relogin.jsp</to-view-id>
      </navigation-case>
   </navigation-rule>‍‍‍‍‍‍‍‍‍‍‍

with

   <navigation-rule>
      <from-view-id>/jsp/*</from-view-id>
      <navigation-case>
         <from-outcome>logout</from-outcome>
         <to-view-id>/jsp/browse/dashboard.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>relogin</from-outcome>
         <to-view-id>/jsp/relogin.jsp</to-view-id>
      </navigation-case>
   </navigation-rule>‍‍‍‍‍‍‍‍‍‍‍

My mistake. Try redirecting logout to index.jsp.

<to-view-id>index.jsp</to-view-id>‍

It sets up the authentication / session as guest user and does the redirect.

Hi,

I did the following changes in teh Faces.config.navigation file..

<navigation-rule>
      <from-view-id>/jsp/*</from-view-id>
      <navigation-case>
         <from-outcome>logout</from-outcome>
         <to-view-id>/jsp/browse/dashboard.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>relogin</from-outcome>
         <to-view-id>index.jsp</to-view-id>
      </navigation-case>
   </navigation-rule>

However, I am still getting the java Exception.. Please suggest as to what is wrong in the code…
