How to process message start parameters?

[jocelyn.duc]

Hello,

I am trying to get working a process starting with a Message Event.

public void testImplicit() {
      KieSession ksession = createKnowledgeSession("message.bpmn2");
       
      Map<String, String> m = new HashMap<String, String>();
      m.put("name", "myName");
      m.put("request", "myRequest");
       
      ksession.signalEvent("Message-StartProcessMessage", m);
}

With this code, my process is starting. The next node is a script task which is printing the given parameters in the console

System.out.println("x: " + x);

The process:

• Variables: x

The message-start node:

• Output: Result
• OutputAssociations: Result->x

Currently, the script node is printing

x: Result

I am expecting a HashMap but Result seems to be a String and I am unable to typecast it, so i can't get the name and the request. I am working on jBPM 6.0.0

Thank you for your help

Jocelyn

The jBPM 5.4 examples contais a jUnit test which do the same, but with a single String parameter... But unable to display it...

So what is wrong? Map/Hashmap is passed as parameter in signalEvent() function, output options are set, and then?
