[jboss-user] [JBoss jBPM] - bject references an unsaved transient instance - save the tr

[rodosa]

Hello, I've a problem in a method that advance in a definition process for the indicated transition. The method is the following:


  | private void goTo(Long id_instance, String transition) {
  | 		try {
  | 			ProcessInstance instance=getJbpmContext().loadProcessInstanceForUpdate(id_instance); 		
  | 			if(!instance.isTerminatedImplicitly()){
  | 				Token token=new Token(instance);
  | 				token.signal(transition);
  | 				
  | 				jbpmContext.save(token);
  | 				jbpmContext.save(instance);
  | 			}
  | 		} catch (RuntimeException e) {
  | 			e.printStackTrace();
  | 		}finally{
  | 			jbpmContext.close();
  | 		}
  | 	}
  | 

And the exception is.


  | 12:40:42,078 ERROR [DbPersistenceService] hibernate commit failed
  | org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: org.jbpm.graph.exe.Token

  | 	at org.hibernate.event.def.DefaultFlushEntityEventListener.dirtyCheck(DefaultFlushEntityEventListener.java:479)
  | 	at

  | 

How could do I fix it?? Because I save both, token and instance. I tried only to save the instance but it didn't work.

Thanks
