Hi Kris,

I hope you can help me.

Here you have the whole code:

public class RuleFlowTest {

    public static final void main(String[] args) {
        try {
            // load up the knowledge base
            KnowledgeBase kbase = readKnowledgeBase();
            StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
            KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
            // start a new process instance
            ksession.startProcess("com.sample.ruleflow");
            System.out.println("Waiting...");
            Person person = new Person();
            person.setName("Kevin");
            person.setSurname("Alonso");
            ksession.insert(person);
            logger.close();
        } catch (Throwable t) {
            t.printStackTrace();
        }
    }

    private static KnowledgeBase readKnowledgeBase() throws Exception {
        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
        kbuilder.add(ResourceFactory.newClassPathResource("ruleflow.rf"), ResourceType.DRF);
        KnowledgeBuilderErrors errors = kbuilder.getErrors();
        if (errors.size() > 0) {
            for (KnowledgeBuilderError error: errors) {
                System.err.println(error);
            }
            throw new IllegalArgumentException("Could not parse knowledge.");
        }
        KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
        kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
        return kbase;
    }

}

Person Class:

public class Person {
    String name;
    String surname;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getSurname() {
        return surname;
    }
    public void setSurname(String surname) {
        this.surname = surname;
    }

}

Kevin,

Could you also post your process, so I can take a look and if necessary
try it out locally to see what is going on?

Quoting Kevin Alonso <kalonso@vicomtech.org>:

  
Hello,
I´m working with a simple flow that has a  Event Wait node. This node

has the following condition:
- Person()

Being Person a class that is not inserted into the session yet.

When the flow arrives to the event wait node its execution stops and
the 
test main class execution continues. Here I insert a Person object to

the session, so now, the flow can continue. After wait node I have a

Split node, which has the followings constraints:

- Person()

- not Person()

The flow always take the not Person() way. But now a Person instance
is 
into the session.

Why is happening this?

Could anyone help me?

Thank you,
Kevin
