      jbossportal 2.7.2

      hi all,

      i am upgrading from jbpm3.2.2 to jbpm3.2.6 in jboss portal 2.7.2.

      i made the following changes

      1. changed the jbpm-identity.jar, jbpm-jpdl.jar
      2. changed the conf/hibernate/workflow/hibernate.cfg.xml
      3. modifed the jboss-portal.sar\portal-workflow.sar/jboss-service.xml

      But the workflow doesnt deploy due to errors below.

      21:10:42,843 ERROR [JobExecutorThread] exception in job executor thread. waiting

            looks the problems seems to be that the JbpmThreadService get started without having a JbpmContext.

            JbpmThreadService .java
            public void start()
             {
             JbpmConfiguration jbpmConfiguration = workflowService.getJbpmConfiguration();
             jbpmConfiguration.getJobExecutor().start();
             }
            
            


            I am not entirely sure why, but once i programmatically call createJbpmContext the JbpmThreadService seems to function without error from then.

             context = workflowService.getJbpmConfiguration().createJbpmContext();
            


            Q1. is expected behaviour with JbpmContext?
            Q2. should client/portlet code be using the workflowservice?
