goschan Posted March 8, 2011 Share Posted March 8, 2011 In my report I have 3 fields that can be displayed several times. I understood that I have to use a sub report. I don't use a database, but a java class that sends the parameters via a HashMap.(see my attachment for the java code)I put $P{map_sub_report} for the "Parameters Map Expression" of my sub report and "Don't pass data" for the "Connection type", but I always have "null" for my sub report. Is someone would be able to help me with this issue ? Link to comment Share on other sites More sharing options...
