REPORT_CONNECTION for SubReport

2003-05-21 00:37

I have made a subreport and use connection expression to define the datasource of subreport. However, the warning message " WARN [dori.jasper.engine.fill.JRBaseFiller] The supplied java.sql.Connection object is null." shows and it cannot be generated the subreport at all. I don't know why it happens while the master report has connection. Thanks.
