Hi, We are trying to run a book server side that runs locally on Jasper Studio and we are experiencing a PART exception when attempting to generate the report. The exception is thrown on net.sf.jasperreports.engine.fill.JRFillSubreport.initSubreportFiller since the book is divided into PART's and not BAND's. Has anyone else experienced this issue by generating the report server side and any workarround on this issue? Many Thanks
