Hi,

i've a little problem with join node during the step from my join node to the next node.

In particular if i have 3 transitions (ex. tr1, tr2, tr3) but only the last one leave the join node, the others 2 are stopped on join node, so when i finished my flow i can see the "end state" on the end node and on the join node.

Are these two transitions stored in the database or create a problem of memory and performance ?




This is an image that shows my flow:

This is the code that forwards the flow:

 public Step[] forwardWF(User user, Step step, Long idWF) {
 JbpmContext jbpmContext = null;
 JbpmConfiguration jbpmConfiguration = null;
 ProcessInstance processInstance = null;
 Step[] steps = null;
 try {
 jbpmConfiguration = JbpmConfiguration.getInstance("WEB-INF/jbpm.cfg.xml");
 jbpmContext = jbpmConfiguration.createJbpmContext();
 processInstance = jbpmContext.getProcessInstance(idWF.longValue());
 if (!processInstance.hasEnded()){
 Token token = processInstance.getRootToken();
 TaskMgmtSession taskSession = jbpmContext.getTaskMgmtSession();
 List listaTask = taskSession.findTaskInstancesByProcessInstance(processInstance);
 Field[] fields = step.getFields();
 boolean trovato = false;
 for (int i = 0; i < listaTask.size()&&!trovato; i++) {
 TaskInstance ti = (TaskInstance)listaTask.get(i);
 if(ti.getId()==Long.parseLong(step.getStepID())){
 for (int j = 0; j < fields.length ; j++) {
 ti.setVariable(fields[j].getId(), fields[j].getValue());
 }
 ti.start("utentegenerico");
 ti.end();
 trovato=true;
 }
 }
 jbpmContext.save(processInstance);
 token = processInstance.getRootToken();
 listaTask = taskSession.findTaskInstancesByProcessInstance(processInstance);
 if(listaTask!=null&& listaTask.size()>0){
 steps = new Step[listaTask.size()];
 for(int i=0; i<steps.length;i++){
 TaskInstance ti = (TaskInstance)listaTask.get(i);
 Step st = new Step();
 st.setStepID(""+ti.getId());
 st.setLocked(false);
 st.setDescrizioneStep(ti.getName());
 st.setFields(getVariables(ti));
 steps=st;
 }
 }else{
 log.info("non ci sono più task");
 steps=new Step[0];
 }
 }
 } catch (Exception e) {
 log.error("errore nel avanzamento del flusso");
 log.error(e,e);
 } finally {
 jbpmContext.close();
 }
 return steps;
 }
