I'm using the local task service with jBPM5.3 version. Question is when I complete the task with contentdata with the following code, the process variable is null. Through kcontext.getVariable("quantity"), I get null. I'm confused about the relationship between the process variables and contentdata.    TaskService client = LocalHumanTaskService.getTaskService(ksession);       Map<String,Object> data = new HashMap<String,Object>();     data.put("priority", request.getParameter("priority"));     data.put("modelNumber", request.getParameter("modelNumber"));     data.put("quantity", request.getParameter("quantity"));     ContentData contentData = null;     if (data != null) {        ByteArrayOutputStream bos = new ByteArrayOutputStream();        ObjectOutputStream out;        try {            out = new ObjectOutputStream(bos);            out.writeObject(data);            out.close();            contentData = new ContentData();            contentData.setContent(bos.toByteArray());            contentData.setAccessType(AccessType.Inline);         } catch (IOException e) {            e.printStackTrace();         }      }          client.complete(taskId, userId, contentData);   Could anyone help me, please? Any help is appreciated. Thank you!
