Hi,  I am newbie to jBPM and I am using JBPM5.2.

I want to program a split process and get exception messages:

Exception in thread "main" java.lang.IllegalArgumentException: XOR split could not find at least one valid outgoing connection for split null

forgive me for my bad english.

Thanks very much.

the source as below:

 public static void main(String[] args) {

  process.addNode(startNode);
  Split splitNode = new Split(Split.TYPE_XOR);
  splitNode.setId(2);
  process.addNode(splitNode);
  new ConnectionImpl(startNode, Node.CONNECTION_DEFAULT_TYPE, splitNode, Node.CONNECTION_DEFAULT_TYPE);
  ActionNode actionNode = new ActionNode();
  actionNode.setName("validUser");
  DroolsAction action = new DroolsConsequenceAction("java", null);
  action.setMetaData("Action", new Action() {
   public void execute(ProcessContext context) throws Exception {
    System.out.println("The user is an valid user.");
   }
  });
  actionNode.setAction(action);
  actionNode.setId(3);
  process.addNode(actionNode);
  Connection validFlow = new ConnectionImpl(splitNode, Node.CONNECTION_DEFAULT_TYPE, actionNode,
    Node.CONNECTION_DEFAULT_TYPE);
  Constraint validConstraint = new RuleConstraintEvaluator();
  validConstraint.setDialect("java");
  validConstraint.setType("code");
  validConstraint.setConstraint("return false;");
  splitNode.setConstraint(validFlow, validConstraint);

  KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

 }
}
