You can try to use jbpm logs. But i don't know which results will you get in
case of the next node is the join node. Here how it is used in TaskBean.java of
jbpm-3.1.3
| LoggingInstance loggingInstance = processInstance.getLoggingInstance();
| List assignmentLogs = loggingInstance.getLogs(TaskAssignLog.class);
|
| log.debug("assignmentlogs: " + assignmentLogs);
|
| if (assignmentLogs.size() == 1) {
| TaskAssignLog taskAssignLog = (TaskAssignLog) assignmentLogs.get(0);
| JsfHelper.addMessage("A new task has been assigned to '" +
taskAssignLog.getTaskNewActorId() + "'");
|
| } else if (assignmentLogs.size() > 1) {
| String msg = "New tasks have been assigned to: ";
| Iterator iter = assignmentLogs.iterator();
| while (iter.hasNext()) {
| TaskAssignLog taskAssignLog = (TaskAssignLog) iter.next();
| msg += taskAssignLog.getActorId();
| if (iter.hasNext())
| msg += ", ";
| }
| msg += ".";
| JsfHelper.addMessage(msg);
| }
|
TaskAssignLog has reference to TaskInstance
