Hi Maciej,
Your proposed approach works fine in terms that the my process now sees the result values.
However, when the time comes for the session to complete the tasks is fails. I suspect the
reason for this is the same – different persistent context.
*private* *void* handleCompletedTask(*long* taskId) {
// currentClient is a reference to my LocalTaskService instance I create for completeting
the tasks
Task task = currentClient.getTask(taskId);
*long* workItemId = task.getTaskData().getWorkItemId();
*if* (task.getTaskData().getStatus() == Status.+Completed+) {
String userId = task.getTaskData().getActualOwner().getId();
Map<String, Object> results = *new* HashMap<String,
Object>();
results.put("ActorId", userId);
*long* contentId = task.getTaskData().getOutputContentId();
*if* (contentId != -1) {
Content content = currentClient.getContent(contentId);
Object result =
ContentMarshallerHelper.+unmarshall+(content.getContent(), session.getEnvironment());
results.put("Result", result);
*if* (result *instanceof* Map) {
Map<?, ?> map = (Map<?, ?>) result;
*for* (Map.Entry<?, ?> entry : map.entrySet()) {
*if* (entry.getKey() *instanceof* String) {
results.put((String) entry.getKey(), entry.getValue());
}
}
}
è fails here
session.getWorkItemManager().completeWorkItem(task.getTaskData().getWorkItemId(),
results);
}
*else* {
session.getWorkItemManager().completeWorkItem(workItemId, results);
}
}
*else* {
logger_processes.debug("session.getWorkItemManager().abortWorkItem()");
session.getWorkItemManager().abortWorkItem(workItemId);
}
}

It seems like either I need to put Drools and Task Service inside the same persistent
context or split the transaction boundaries between Drools and Task Service. The second
one is in fact a recommended way here which has been previously discussed in another
posts, but I strongly disagree with the Task Service decoupling idea.
Any other thoughts/ideas?
Thanks,
Vladimir
