Pessoal...

Não sei mais como resolver esse problema. Segui milhoes de tutorias mas, nenhum deles serviu para solucionar o meu problema.

Vamos lá...

1-Tenho uma entidade mapeada assim:




2-Faço uma consulta de todas as turmas

3-Ao editar alguma turma apresenta esse erro:

Pessoal...

Tenho lido que posso evitar essa exceção aumentando o tempo de vida de meus beans, ou seja, o escopo.

Pra teste, coloquei o scope como session mas, a exceção continua apresentando.

Não tem nada haver com o escopo do seu MB.

Vc sabe para que serve o Lazy que você tanto colocou?


Quando você recupera esse objeto no DB e envia para página, nenhum deles ainda foi carregado e como eles estão na página a sessão do DB já foi encerrada (caso não use Open Session in View).

Pq você não faz um teste, arranca todos os Lazy.

Amigo,

coloca no seu método do editar isso...

turma = seuDao.getById(turma.getNuTurma());

Assim ele vai abrir uma nova sessão e vai recuperar o objeto.

Faço isso aqui e sempre resolveu.

Abraço.
