Olá pessoal!

Estou tentando realizar um teste de um modelo de cadastro em JSF, porém estou com erros. Estou utilizando Primefaces 2.2.1 Primeiramente a estrutura do projeto:

Agora o que está acontecendo:
1- Quando coloco no xhtml apenas p:commandButton (mais especificadamente quando deixo as linhas 190 a 196) não há erro algum.
2- Quando coloco as linhas que possuem p:inputText, quando vou rodar a aplicação, o seguinte erro aparece:

Procurei aqui no fórum porém não achei nada parecido. Alguém tem alguma idéia do que pode estar errado?
Obrigada!

Tente trocar o escopo.

@ManagedBean(name="teste") @ViewScoped
Para.

@ManagedBean(name="teste") @SessionScoped

E outra dica use as convencoes de codigo java.

Troquei o escopo mas o erro continua…

Poste o final de seu stacktrace. Se o erro nao for se repetindo assim, mas pegue do local que ele para de repetir ate o final ou se preferir coloque todo stacktrace aqui.

Pessoal, estava com (exatamente) o mesmo problema. Todavia, comecei a desenvolver utilizando @SessionScoped.
“Consegui” resolver o problema removendo a annotation @SessionScoped…

Seria um problema deixar o sistema assim?
