[jboss-user] [JBoss jBPM] - How to take a decision in java code

[Jean-LucT]

I'm new to jBPM 3.2.1 but I didn't find anything on this subject either in doc/examples and this forum : still my question seems to me very basic.

I want to be able to decide the transition I will follow in a piece of Java Code according to the data previously entered.

I'm using a Decision node for this with two transition (Oui and Non).
I've added an action/"Node Enter". This action map a java class using the field setup.

My java code : 
public class DecideIfCustomer implements ActionHandler {
  | 	private static final Logger logger = Logger.getLogger(IsCustomer.class);
  | 
  | 	public DecideIfCustomer() {
  | 		super();
  | 	}
  | 
  | 	public void execute(ExecutionContext executionContext) throws Exception {
  |         Node node = executionContext.getNode();      	
  | 		ContextInstance contextInstance = executionContext.getContextInstance();
  |         if (contextInstance.getVariable("Nom du contact").equals("Non")) {
  |             node.leave(executionContext, "Non");
  |         }
  |  	}
  | 
  | }
  | 

Notice that my class is an instance of ActionHandler because I've not been able to use a DecisionHandler. When using a DecisionHandler I got a ClassCastException.

With this, I'm able to go through the transition Non when my variable is correctly set BUT : I noticed that in fact it takes the Non transition twice and then go to the Oui transition.

I guess I missed something, anyhelp ?

My process-definition for the decision node :
   <decision name="Client actif ?">
  |       <event type="node-enter">
  |          <action name="isCustomerAcitf" class="fr.jl2tho.tutorialjbpm.action.DecideIfCustomer"></action>
  |       </event>
  |       <transition name="Oui" to="Enregistrer la Question"></transition>
  |       <transition name="Non" to="Prevenir le commercial"></transition>
  |    </decision>
