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

[janardhana p]

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.
