Hi,
If i understood correctly, you can return results from your custom work item by passing your parameters to the
completeWorkItem(WorkItem workItem, WorkItemManager manager, Map<String, Object> results) method of WorkItemManager object
i.e.
Map<String, Object> results;
results.put("result", resultObject); results.put("error",errorObject);
manager.completeWorkItem(workItem.getId(), results);
or even better from the StatefulKnowledgeSession object via
ksession.getWorkItemManager().completeWorkItem(....) .
Then you can assign the result mapping i.e from editors.
