Olá gente…
To com um seguinte problema…
Estou tentando fazer um relatorio com Ireport 4.0.2, e tenho um objeto em que um do seus atributos é uma lista…
Como que faz pra iterar uma lista no Ireport???
Ja tentei usar ==== > new JRBeanCollectionDataSource(minhaColecao); mas erro de conversao!!!
Tentei tambem fazer um SUBREPORT… MAS DA ERRO DO MESMO JEITO
To desesperado… ja procurei alguns foruns e guides, mas nao fala nada de JAVA.UTIL.LIST em ireport…
Alguem pode me passar um tutorial ou dica!!!
