问题
I'm currently new using iReport to create reports.
My main report is just one long page with many subreports. Every time I run my subreports alone with no data it says no pages, but with my main report, it shows blank pages. I want it to show only the pages with data, and those pages without data should not have blank pages.
I placed my subreports in report groups:
Group
Subreport
Subreport
Group
and it is repeated at around 5-6 times. I have already set all of my reports including my main report the When no data = No Pages, and I have also checked the remove line when blank in the common properties for all subreport elements. My main report does not have a query so I placed a simple SELECT 1.
P.S. I can't post my code due to the fact that I'm not allowed to export and import code in the office.
回答1:
you need to go to edit query of your subreport and set the record node (Xpath generation).....it will remove the problem of subreport that is NO PAGES IN DOCUMENT...
