    Are Seam jBPM's annotations of @StartTask and @BeginTask duplicated?

      Hi all,
      I am confused about the two annotaitons of @StartTask and @BeginTask. It seems that they do the same job. I check the BusinessProcessInterceptor which process these two annotations and found:



       if ( method.isAnnotationPresent(StartTask.class) ) 
      {
         log.trace( "encountered @StartTask" );
         StartTask tag = method.getAnnotation(StartTask.class);
         Long taskId = getProcessOrTaskId( tag.taskIdParameter(), tag.taskId() );
         return BusinessProcess.instance().resumeTask(taskId);
      }
      else if ( method.isAnnotationPresent(BeginTask.class) ) 
      {
         log.trace( "encountered @BeginTask" );
         BeginTask tag = method.getAnnotation(BeginTask.class);
         Long taskId = getProcessOrTaskId( tag.taskIdParameter(), tag.taskId() );
         return BusinessProcess.instance().resumeTask(taskId);
      }


      At the backend, they all resume a task. So, why we need two annotations here? Are they actually same? Thanks.

          Not really the same. The StartTask annotation do this on the afterInvocation part:


           if ( method.isAnnotationPresent(StartTask.class) ){
            log.trace( "encountered @StartTask" );
            BusinessProcess.instance().startTask();
}



          The difference is that with this the StartTask this will set the start time, assign the actor current actor and fire any task-start events defined.
