Olah pessoa! minha duvida eh a seguinte... tenho uma aplicacao web q gera varios relatorios utilizando collections mas oq ocorre eh q somente eh exibido um regitro por vez!! pra q a aplicacao "enchergue" os novos registr…

Olá. Verifique se os commits estão ocorrendo certo. Posta o código da sua classe que popula as collections aqui no fórum, ai fica mais fácil dizer o que pode ser.

Como assim??? tem algo mtooooo errado ai… Poe os codigos ai…
