    this token is locked by token[34]

    darkzan Newbie

      hello,

      i'm new in the jbpm world and trying to understand how it works,

      while trying to end a taskinstance by using taskinstance.end();

      i keep getting the exception "this token is locked by token"

       

      my method

      public void completerTask(long id) {
              JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
              JbpmContext jbpmontext = jbpmConfiguration.createJbpmContext();
              TaskInstance task = jbpmontext.getTaskInstance(id);
              task.end();
              jbpmontext.close();
          }
