Description of problem:

When accessing the Export/Import gadget from a custom portal container and a Javascript alert with the error message "Failed to load sites available for export. See server log for more details." should appear. In the logs we can see the following error:

ERROR [org.gatein.management.gadget.mop.exportimport.server.IdentityFilter] (http-/127.0.0.1:8080-5) Conversation state not found. This typically means the GWT Gadget application is either being access anonymously or from outside the portal.


How reproducible:

Easy to reproduce using the quickstarts

Steps to Reproduce:
1. Deploy the sample-portal container in JPP 6.0
2. Access the new container and log in as root
3. Access the site Export/Import gadget in URI /g/:platform:administrators/administration/siteExportImport

Actual results:

A Javascript alert with the error message "Failed to load sites available for export. See server log for more details." will appear. In the logs we can see the following error:

Expected results:

Gadget working and able to export/import sites.

Additional info:

It starts with a 401 in gwtGadgets/exportimport/GateInService

Request URL:http://localhost:8080/gwtGadgets/exportimport/GateInService
Request Method:POST
Status Code:401 Unauthorized 

Which is causing this is the servlet filter in [1]. It's is set in file [2]. Seems that A ConversationState isn't being created for this container.

       ConversationRegistry conversationRegistry =
               (ConversationRegistry) container.getComponentInstanceOfType(ConversationRegistry.class);
 
       ConversationState state = conversationRegistry.getState(stateKey);
       if (state == null) {
           log.error("Conversation state not found. This typically means the GWT Gadget application is either being access anonymously or from outside the portal.");
           handleError(httpRequest, httpResponse, 401);
           return;
