Resetting $V{REPORT_COUNT} for each group in Jasper reports

I am using $V{REPORT_COUNT} in JasperReports to print serial number and it works well. But when I grouped by a field and started each group on a new page the serial number still continues across the groups.

I need to reset this variable $V{REPORT_COUNT} for each group.

Thanks.

Solution

  • If you want a count that resets on each page, then that's not $V{REPORT_COUNT} by definition.

    It sounds like you want the built-in variable $V{PAGE_COUNT}. Or you might want the built-in $V{MyGroup_COUNT}.

    More generally you could create your own variable to count what you want. But the built-in ones probably meet your needs in this case.
