hi, i am working on jasperBI3.7 and trying to use subreports, i have 2 JRXML's based on a parameter value i am trying to execute either of them.i have tried all possible ways to get this running,it seems like without adding a dummy field to the master report from domain the subreport doesnt work, it throws null pointer exception. I Thik this is a serious bug in jasperserver3.7 and none of your ultimate guides are helping,I request one of you to answer my query and explain whether its a bug in subreport or explain how to use subreport. I have searched the entire forum for similar problem and didnt find any suitable answer. this is a serious set back my team is facing as we have adopted jasperserver 3.7 to develop reports.
