Hello, I created jasper report and it runs perfectly on jasperserver, also export is fine to XLS pr XLSX from jasperserver. Problem is when i call jasperreports REST server API and export report to XLS or XLSX using rest API. I noticed same is with report in PDF format. I got report where in every new page rowGroups are repeated, i upload attachment how it looks. Just to be clear, report is good in all formats when i run and export it using jasperserver directly. Is there some special property i need to set when calling jasperserver rest api, in order to get valid exported report? Any help will be appreciated, as i am struggling with this problem for a while.
