I have a report made with ireport 6.0.1, I have to modify the not compatible content to open it with 4.1.1 version. I deleted the uuid, borderSplitType="DrawBorders" on the frames, now I have the evaluationTime="Master" property, should it be changed to evaluationTime="Report"?
PS : I didn't find any documentation on the differences between the two versions.
Configuring Jaspersoft Studio to Source .jrxml version 4.1.1 should automatically modify the source as needed to be compatible with 4.1.1.
Further:
EvaluationTimeEnum in 4.1.1: https://javadoc.io/static/net.sf.jasperreports/jasperreports/4.1.1/net/sf/jasperreports/engine/type/EvaluationTimeEnum.html
EvaluationTimeEnum in 6.0.0: https://javadoc.io/static/net.sf.jasperreports/jasperreports/6.0.0/net/sf/jasperreports/engine/type/EvaluationTimeEnum.html
Please also have a read of Chapter "7.3.1 Evaluation Time" in the current 'TIBCO Jaspersoft Studio User Guide' https://community.jaspersoft.com/documentation/v8-v80-v800/tibco-jaspersoft-studio-user-guide to get a better understanding of Evaluation Time.
