Hi, I have 3 reports using JRDataSourceProvider as DataSource and they are working fine when I execute them individually. As per design, I need to call these reports from a Master report but when I do that, I am getting an empty report. Master report also use the same datasoure and it returns some records. For parameter "Connection/DataSourceExpression" I am passing $P{REPORT_DATA_SOURCE}. Need some help on resolving this? I am using iReport 1.3.3 to create these reports. Note:- I have few other reports working fine. The only difference is they all are using Database JDBC Connection.
