      Hi,

      I made a processdef like this:
      <process-definition name="Processus qualité2"+
      <start-state name="start">
      transition name="To_analyse_transition' to='Task_byPM"
      </start-state>
      <task-node name="Task_byPM">



      and it's well deployed,
      then when i execute the code:
      ______________________
      JbpmSession jbpmSession = jbpmSessionFactory.openJbpmSession();
      //GraphSession graphSession = jbpmSession.getGraphSession();
      jbpmSession.beginTransaction();
      ProcessDefinition processDefinition = jbpmSession.getGraphSession().findLatestProcessDefinition(requestParam.getRequestType());
      ProcessInstance processInstance = new ProcessInstance(processDefinition);



      // ContextInstance: process variables :)
      ContextInstance contextInstance = processInstance.getContextInstance();
      contextInstance.setVariable("Commentaire de l'utilisateur final", requestParam.getComment());
      contextInstance.setVariable("ProjectManager", requestParam.getProjectManagerID());
      contextInstance.setVariable("Nom du projet", requestParam.getProjectName());
      contextInstance.setVariable("Type requête", requestParam.getRequestType());

      processInstance.signal("To_analyse_transition");


      jbpmSession .getGraphSession().saveProcessInstance(processInstance);
      jbpmSession.commitTransaction();
      jbpmSession.close();

      i have the following error :(
      java.lang.NullPointerException
