Hi, I have a master report with a Title and 4 subreports, for now. All my subreports are in column header in the mail report and in No Data section otherwise. Now when I generate the report from my UI, the report gets generated but only the Title gets printed on it. In my iReport properties for the subreport, I have set the Expression class as JasperReport type and my subreport expression is $P{Permit_Details_Subreport}. If I make the expression class String, nothing gets printed even then. Please let me know if you need any other info. Can anyone tell what I am doing wrong please. Thanks J
