Несколько таблиц в dynamicJasper с использованием addConcatenatedReport

Question

Кто-нибудь знаком с dynamicJasper? Я пытаюсь создать несколько таблиц в одном отчете, используя подотчет. Однако я не могу понять это. Я продолжаю получать ошибки. Одна из ошибок, которые я получил недавно,

Error: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : 
    Source text : new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource((java.util.Collection)$P{REPORT_PARAMETERS_MAP}.get( "cs" ) )

Примечание: я получаю мои Коллекции / данные из 2 таблиц в моем классе контроллера, которые я использую для заполнения содержимого моих таблиц. Пожалуйста помоги. Заранее спасибо.

Это мой класс отчета:

public class CustomersReportPrintReport {
    private final Collection<SalesData> customerlist = new ArrayList<>();
    private final Collection<SalesData> loanlist = new ArrayList<>();
    private final String fromDate;
    private final String toDate;
    SalesData salesData = new SalesData();
    HashMap params = new HashMap();
    JRBeanCollectionDataSource ds1 = new JRBeanCollectionDataSource(customerlist);
    JRBeanCollectionDataSource ds2 = new JRBeanCollectionDataSource(loanlist); 


    public CustomersReportPrintReport(Collection<SalesData> customerList, Collection<SalesData> loanList, LocalDate fromDate, LocalDate toDate) {
        //change date format
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("MMMM dd, yyyy");
        String fromDateString = dtf.format(fromDate); 
        String toDateString = dtf.format(toDate);
        //assign variables
        this.customerlist.addAll(customerList);
        this.loanlist.addAll(loanList);
        this.fromDate = fromDateString;
        this.toDate = toDateString;
    }

Это мой класс контроллера:

            JasperViewer jasperViewer = new JasperViewer(jp, false);
            jasperViewer.setVisible(true);

        } catch (JRException | ColumnBuilderException | ClassNotFoundException ex) {
            System.out.println("Error: " + ex);
        }
    }
