Hibernate + JSF Erro ao persistir objeto

Henrique_Greg · Outubro 30, 2016, 11:37pm

Olá Pessoal, estou tentando salvar um objeto no banco Mysql com o Hibernate.
Porém quando eu preencho os dados na tela de cadastro eu recebo um erro dizendo que a transação já está ativa
Obs. Percebi que quando eu requisito a url no navegador, o console mostra um sql gerado pelo hibernate. (Apenas requisistando a página)

Outra observação é que a listagem dos objetos já cadastrados funciona normalmente.
(Inclusive a página de cadastro estava funcionando pois foi assim que eu inseri os dados) deu esse erro derepente… já desliguei o pc troquei a versão do tomcat e nada…

Erro no Navegador

Olá! Interessante debugar o fluxo da aplicação pra ver se não está sobrando alguma transação pendente, mas caso queira algo rápido, o que não resolve o problema da transação sobrando, mas reaproveita a mesma, é:

if(!em.getTransaction().isActive())
        em.getTransaction().begin();
em.persist(f);
em.getTransaction().commit();
em.close();
