[jboss-user] [JBoss jBPM] - define process definition with jbpm's api

[jnesta]

jbpm3.1.2

I define process as follows:

  | ProcessDefinition definition = new ProcessDefinition();
  | definition.setName("hello world");
  | 
  | Transition open = new Transition("open");
  | open.setProcessDefinition(definition);
  | 
  | StartState newS = new StartState("new");
  | newS.addLeavingTransition(open);
  | 
  | State openS = new State("open");
  | openS.addArrivingTransition(open);
  | 
  | open.setFrom(newS);
  | open.setTo(openS);
  | 
  | EndState end = new EndState("close");
  | 
  | Transition close = new Transition("close");
  | close.setFrom(openS);
  | close.setTo(end);
  | close.setProcessDefinition(definition);
  | openS.addLeavingTransition(close);
  | end.addArrivingTransition(close);
  | 
  | definition.setStartState(newS);
  | definition.addNode(openS);
  | definition.addNode(end);
  | 
I can deploy it successfully, but when I store variables in new process instance, it fails.

  | 		GraphSession gs = jbpmContext.getGraphSession();
  | 		ProcessDefinition pd = gs.findLatestProcessDefinition("hello world");
  | 		ProcessInstance pi = new ProcessInstance(pd);
  | 		ContextInstance ci = pi.getContextInstance();
  | 		ci.setVariable("name", "jnesta");
  | 		jbpmContext.save(pi);
  | 		jbpmContext.close();
  | 

But it runs successfully when parse process string like jbpm's "hello world" example.

So I think that I miss something in process definition.

Thanks in advance.
