    jBPM 4.3, Spring 2.5, Oracle, start process, process instance have a null id

    topiltzin May 14, 2010 11:35 AM

      When I try to start a new process instance, and then go to next state, the process instance its created
      as I can see it in the DataBase, but the ID of the process instance is null, I need some help, why is this happenning?

       

      The code:

       

      ProcessInstance processInstance = getExecutionService()
              .startProcessInstanceByKey(processDefinitionId);

       

      String processInstanceId = processInstance.getId();
      logger.debug("processInstanceId: " + processInstanceId);

       

      and ... processInstanceId is null as I can see in the DB, thanks in advance

          my guess is you forgot

           

          <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" />

           

          but this is hard to tell without seeing your complete configuration

            Excellent, I was trying to solve this 2 days ago, thanks!!!

             

            As you said, I just add: <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" />

            to my jbpm.cfg.xml file

             

            Here is the configuration:
