数据不会出现在eclipse Birt中的DataSet中

Question

！[在此处输入图片说明] [2]我使用eclipse Birt报告构建的应用程序是apache ofbiz。我想以表格格式报告一些信息，并希望以pdf格式获取输出，这是我的目的。我发布的是从源中获取数据的类..

 public static void getReport(HttpServletRequest request, HttpServletResponse response){
    Delegator delegator = (Delegator) request.getAttribute("delegator");
    String reportType = request.getParameter("reportType");
    String compId = request.getParameter("companyId");

    List empTaskLists =  FastList.newInstance();

    //check employee position
    try {
        //use Company Id from global context
        List<GenericValue> partyList = EntityUtil.filterByDate(delegator.findByAnd("PartyRelationshipAndDetail", UtilMisc.toMap("partyIdFrom", compId)));
        //child
        for( GenericValue party : partyList) {
            GenericValue partyInfo=delegator.findByPrimaryKey("PartyAndPerson", UtilMisc.toMap("partyId", party.get("PartyId")) );
            String partyName = partyInfo.get("firstName") +" "+partyInfo.get("lastName");      

            List<GenericValue> taskList = delegator.findList("WorkEffortAndPartyAssign", EntityCondition.makeCondition(UtilMisc.toMap("partyId", party.get("partyId"), "currentStatusId", "PTS_CREATED" , "statusId", "PAS_ASSIGNED")), null, null, null, false);

            for( GenericValue task : taskList) {

                Map taskMap = FastMap.newInstance();
                String taskName=task.getString("workEffortName");

                    taskMap.put("empId", party.get("partyId"));
                    taskMap.put("empName", partyName);
                    taskMap.put("taskName", taskName);
                    taskMap.put("start", task.get("estimatedStartDate"));
                    taskMap.put("end", task.get("estimatedCompletionDate"));

                    empTaskLists.add(taskMap);
            }   


        }


    } catch (Exception e) {
        e.printStackTrace();
    }

这个类负责将数据填充到birt.And在Birt我有一个空的数据集。我发布了open和fetch脚本

打开脚本

var compId= "DemoScrumCompany"; 
emptaskList = FastList.newInstance();

partyList = delegator.findList("PartyRelationshipAndDetail",      EntityCondition.makeCondition(UtilMisc.toList("partyIdFrom",compId)),null, null, null, false);

//child
  for( party in partyList) {
 partyName = PartyHelper.getPartyName(party, true);      
  var conds = FastList.newInstance();
  conds.add(EntityCondition.makeCondition("partyId", EntityOperator.EQUALS,   party.get("partyId")));
conds.add(EntityCondition.makeCondition("currentStatusId", EntityOperator.EQUALS, "PTS_CREATED"));
conds.add(EntityCondition.makeCondition("statusId", EntityOperator.EQUALS, "PAS_ASSIGNED"));

taskList = delegator.findList("WorkEffortAndPartyAssign", EntityCondition.makeCondition(conds), null, null, null, false);
for( task in taskList) {
    taskMap = FastMap.newInstance();
    taskName=task.get("workEffortName");
    //taskName="Task1";
    taskMap.put("empId", party.get("partyId"));
    taskMap.put("empName", partyName);
    taskMap.put("taskName", taskName);
    taskMap.put("start", task.get("estimatedStartDate"));
    taskMap.put("end", task.get("estimatedCompletionDate"));
    //taskMap.put("empId", "EMp01");
    //taskMap.put("empName", "EMP1");
    //taskMap.put("taskName", taskName);
    //taskMap.put("start", "2014-05-21");
    //taskMap.put("end", "2014-05-31");
    emptaskList.add(taskMap);
}   

 }
totalRow = 0;
countOfRow = 0;

  if (emptaskList.size()> 0 ) {
  totalRow = emptaskList.size();
} 

获取脚本

  if (countOfRow < emptaskList.size()-1) {

var emptaskMap =emptaskList.get(countOfRow);
row["employeeId"] = emptaskMap.get("employeeId");
row["employeeName"] = emptaskMap.get("employeeName");
row["taskName"] =emptaskMap.get("taskName");
row["startDate"] = emptaskMap.get("startDate");
row["endDate"] = emptaskMap.get("endDate");
countOfRow++;
return true;
}

return false;

这些我已经完成了数据。它足够了????。我还有一个数据集，我已经附在图片中。我需要用数据填充数据集
