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.
