javax.transaction.RollbackException when creating navigation node in GateIn
---------------------------------------------------------------------------

                 Key: GTNPORTAL-855
                 URL: https://jira.jboss.org/jira/browse/GTNPORTAL-855
             Project: GateIn Portal
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: GateIn trunk (revision 2083) deployed on EAP5,
Sun JDK 1.6,
MySQL 5.1 shared database (between two GateIn nodes)
            Reporter: Marek Posolda
             Fix For: 3.1.0


I have a problem when having two GateIn instances on different servers running in cluster. Steps to simulate:

1) Run node1 with -Dexo.profiles=cluster
2) Run node2 with -Dexo.profiles=cluster
3) Login as root in node1 and go to portalnavigation -> Edit navigations -> Add node -> Use existing page in page selector (portal::classic::homepage) -> Fill node name and title -> click to Save
4) Now I am able to see my new node. But I can see exceptions in server logs in both node1 and node2. 

Exception on node2 is "[TxInterceptor] prepare failed! java.lang.NullPointerException". 

Exception on node1 is "[TxIsolatedOperation] Transaction has been rolled back javax.transaction.RollbackException: [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] Could not commit transaction."


Full stacktraces of both exceptions are attached. Interesting is that I am also able to see the page on second node. So it seems that nothing happens in application itself, only exceptions in server logs are strange. Exception on node2 (NullPointerException) occurs first and exception "RollbackExcption" on node1, where new navigations were created, occurs after it. And I can see only when having cluster with more nodes. It doesn't occur in single node.

For completeness: I am using shared database MySQL with JBoss datasources in server/production/deploy directory and "no-tx-datasource" datasource. Both nodes are executed with "-Dexo.profiles=cluster". I am attaching my server/production/conf/gatein/configuration.xml.
