Hi Teodor, thanks for the post. I will try to give you more details: - my master report actually doesn't use the datasource. I need it only for the subreport. :) Therefore I have to pass somehow the parameter from the master to the subreport. - with the command $P{REPORT_DATA_SOURCE}.toString in a text field i found out that the subreport gets the same object like the master. - if I use the same subreport as a master report it works and the datasource is read, but this is not the case when it is a subreport. - through some testing (using new JRDataSource($P{REPORT_DATA_SOURCE}) as the value for the Datasource Expression) I found this code snipplet: value = (net.sf.jasperreports.engine.JRDataSource)(new JRDataSource(((net.sf.jasperreports.engine.JRDataSource)parameter_REPORT_DATA_SOURCE.getValue()))); I am wondering what parameter_REPORT_DATA_SOURCE.getValue() does when the class type of this parameter is JRDataSource and this interface doesn't have a getValue() method? Thank you very much for answering and helping. Best, Miro.

Hi, I'd like to include a subreport using JRCsvDataSource in a master report's summary band. I compile both the reports and then fill the master one using JasperFillManager.fillReportToStream(in, out, params, dataSource); but the subreport doesn't show. ?? Any idea why that could be ?? I have already set the datasource expression of the subreport to $P{REPORT_DATA_SOURCE} so that it has it, but still... Thanks, miro
