a master report with 2 subReports that loops infinitively when filled

[flamant]

Hi, I definitively have some problems with subreports

Here is a master report with 2 subreports that are in a group

When I fill the master report as the following


            Map simpleMasterMap = new HashMap();
            Map subreport2 = new HashMap();
            subreport2.put("subReportJasperReport", subReportQueryJasperReportList.get(1));
            subreport2.put("subReportDataSource", subReportQueryDataSourceList.get(1));
            simpleMasterMap.put("subReportName", subReportName.get(1));
            simpleMasterMap.put("subReportJasperReport", subReportJasperReport.get(1));
            simpleMasterMap.put("subReportDataSource", subReportDataSource.get(1));
            simpleMasterMap.put("subreport2", subreport2);
            simpleMasterList.add(simpleMasterMap);



        JRDataSource simpleDS = new JRMapCollectionDataSource(simpleMasterList);


        HashMap SIMPLE_DATA = new HashMap();
        params.put("SIMPLE_DATA", SIMPLE_DATA);


        JasperPrint jasperPrint = null;
        InputStream jrxmlInputStream = new ByteArrayInputStream(jrxml.toString().getBytes());
        if (simpleDS == null)
            simpleDS = new JREmptyDataSource(1);

        try {
            JasperDesign jasperDesign = JRXmlLoader.load(jrxmlInputStream);
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            jasperPrint = JasperFillManager.fillReport(jasperReport, params, simpleDS);



it loops infinitively with the following output

<field name="subReportJasperReport" class="net.sf.jasperreports.engine.JasperReport"/>

should be a parameter not a field.

<parameter name="subReportJasperReport" class="net.sf.jasperreports.engine.JasperReport"/>
