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
