Bem eu estou com um problema e não tenho ideia de como corrigi-lo, estou começando a mexer com o hibernate.
Tenho duas tabelas
Produto e Local
Para cadastrar um produto eu preciso fornecer um local, ateh ai tudo bem ele cadastra o problema eh na hora de fazer o update
Eu carrego os itens na minha tela, mas o atributo local exibe no debug com.sun.jdi.InvocationException occurred invoking method e org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer@5fada2
E na tela exibe isso aqui
HTTP Status 500 - javax.el.ELException: /admin/cadastrobicicleta.xhtml @17,61 value="#{bikeBean.produto.local.id}": Error writing 'id' on type br.com.bikers.model.local.Local_$$_javassist_1
