No tópico "Passando Datasources para sub relatórios" há a explicação apenas sobre como passar o dataSource para o relatório principal.
JasperPrint print = JasperFillManager.fillReport(jr, params, dataSource);Mas quando o relatório principal possui vários objetos incoporados? Gráficos, Subrelatórios, Crosstab .... Como passar os dataSources de cada um deles?
