I have this report with the main query and 6 subdatasets to use with crosstab component. I can upload the jrxml to the server directly. But when I try to do that within ireport it gives me error (Error: 1-0). With only two subdatasets works just fine. More than two doesn't let me upload within ireport. I am using Ireport 3.7.6. Have tried with Ireport 3.7.1 and the same error happens. Is it a limit of IReport or JasperServer? What am I doing wrong?
