[jboss-user] [jBPM] - ProcessEventListener methods executed twice

Sebastien Lelarge [http://community.jboss.org/people/slelarge] created the discussion "ProcessEventListener methods executed twice" To view the discussion, visit: http://community.jboss.org/message/632356#632356 -------------------------------------------------------------- Hi, I am playing with ProcessEventListener implementation and I have the feeling that methods are executed twice for the same Node. For now, I am just tracing a message when a method is triggered and I get it twice in the log file ! My goal is to fire rules when I reach a Rule Task Node because I have issues if I fireAllRules at process startup... What's wrong ? Here's how I initialize the ksession {code} ksession =  JPAKnowledgeService.newStatefulKnowledgeSession(base, kconfig, JPAWorkingMemoryDbLogger wkfLogger = new JPAWorkingMemoryDbLogger(ksession); ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new CommandBasedWSHumanTaskHandler(ksession)); ksession.addEventListener(new JbpmProcessEventListener(ksession)); {code} here's the code of my EventListener: {code} import org.drools.event.process.ProcessCompletedEvent; import org.drools.event.process.ProcessEventListener; import org.drools.event.process.ProcessNodeLeftEvent; import org.drools.event.process.ProcessNodeTriggeredEvent; import org.drools.event.process.ProcessStartedEvent; import org.drools.event.process.ProcessVariableChangedEvent; import org.drools.runtime.StatefulKnowledgeSession; import org.jbpm.workflow.core.node.RuleSetNode; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class JbpmProcessEventListener implements ProcessEventListener {                 private StatefulKnowledgeSession session;                 private static Logger logger = LoggerFactory.getLogger(JbpmProcessEventListener.class);                 public JbpmProcessEventListener(StatefulKnowledgeSession ksession){                                session = ksession;                 }                 public void beforeVariableChanged(ProcessVariableChangedEvent event) {                 }                 public void beforeProcessStarted(ProcessStartedEvent event) {                 }                 public void beforeProcessCompleted(ProcessCompletedEvent event) {                 }                 public void beforeNodeTriggered(ProcessNodeTriggeredEvent event) {                     logger.debug("beforeNodeTriggered: " + event.getNodeInstance().getNode().getClass());                     logger.debug("beforeNodeTriggered: " + event.getNodeInstance().getNode().getName());                     if (event.getNodeInstance().getNode() instanceof RuleSetNode) {                         session.fireAllRules();                     }                 }                 public void beforeNodeLeft(ProcessNodeLeftEvent event) {                  }                 public void afterVariableChanged(ProcessVariableChangedEvent event) {                 }                 public void afterProcessStarted(ProcessStartedEvent event) {                 }                 public void afterProcessCompleted(ProcessCompletedEvent event) {                 }                 public void afterNodeTriggered(ProcessNodeTriggeredEvent event) {                 }                 public void afterNodeLeft(ProcessNodeLeftEvent event) {                 } } {code} -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632356#632356] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
