Boa noite, tenho o seguinte contexto:
Minha aplicacao utiliza JSF2, CDI e PrimeFaces, minha view esta rendenizando normalmente, porem, caso eu venha a acionar um F5 repetidas vezes acaba me retornando o erro de Rendering View com NullPointerException, minha view esta anotada com @ViewScoped caso eu mude para @Request o problema acaba.
