Re: [jasperreports-questions] Compatibility Problem i_Report_0_2_3 and i_Report-0.5.1

Thu, 17 Nov 2005 23:18:02 -0800 

Hi

Your error is due to a bug (#1290957) that was fixed in JasperReports 1.0.3.
iReport 0.5.1 comes with JR 1.0.1, you could download JR 1.0.3 and replace it in the iReport lib directory. 

HTH,

Hi,
We have compiled the old report files with i_Report-0.5.1. We are getting the following exception when there is a subreport in title page section and 
the main query(report) returns 0 rows.

If we move subreport from title section to summary section then the report is working fine. 
Please throw some light on this to resolve this problem.

Thanks in Advance.
