Pessoal estou com a seguinte duvida,
Tenho uma datatable que lista os meus usuarios cadastrados, mas percebo que ele só lista se estiver na sessão. Tipo, se eu cadastrar e listar eles substitui todas as linhas anteriores por meu usuairo inserido no momento. Se eu não cadastrar ele mostra as linhas em branco. As linhas em branco que falo são as linhas que cadastrei das vezes anteriores.
Alguem sabe decifrar esta?
Grato!
posta o faces-config e o bean.
Segue o managed bean:
[code]public class UsuarioBean {
private Usuario usuario;
private Endereco endereco;
private Login login;
@SuppressWarnings("unchecked")
private UsuarioDAOImpl usuarioDaoImpl;
@SuppressWarnings("unused")
private String resultado;
private List<Usuario> usuarios;
//getrs e setrs...
public String limparCampos() {
usuario.setId(null);
usuario.setNome("");
usuario.setTelefone("");
usuario.setIdade(null);
usuario.setDataNascimento(null);
endereco.setRua("");
endereco.setNumero(null);
endereco.setCep("");
endereco.setBairro("");
endereco.setCidade("");
endereco.setPais("");
login.setId(null);
login.setNomeLogin("");
login.setSenha(null);
return "Sucesso";
}
@SuppressWarnings("unchecked")
public String salvar() {
endereco.setUsuario(usuario);
login.setUsuario(usuario);
usuario.setEndereco(new HashSet<Endereco>());
usuario.getEndereco().add(endereco);
try {
usuarioDaoImpl.salvar(usuario);
resultado = "Sucesso";
} catch (Exception e) {
resultado = "Insucesso";
e.printStackTrace();
}
return resultado;
}
@SuppressWarnings("unchecked")
public String atualizar() {
endereco.setUsuario(usuario);
login.setUsuario(usuario);
usuario.setEndereco(new HashSet<Endereco>());
usuario.getEndereco().add(endereco);
try {
usuarioDaoImpl.salvarOuAtualizar(usuario);
resultado = "Sucesso";
} catch (Exception e) {
resultado = "Insucesso";
e.printStackTrace();
}
return resultado;
}
@SuppressWarnings("unchecked")
public List<Usuario> getUsuarios() {
usuarios = new ArrayList<Usuario>();
usuarios = usuarioDaoImpl.listar();
return usuarios;
}
}[/code]
Segue o applicationContext.xml:
[code]<?xml version="1.0" encoding="UTF-8"?>
<aop:aspectj-autoproxy />
<!-- DECLARAÇÃO DO MANAGED BEAN -->

Caro Ánderson Bonnavides por acaso o senhora ja procurou no Google ou na Documentação do Hibernate ou até mesmo no próprio guj?
Indicates access to unfetched data outside of a session context. For example, when an uninitialized proxy or collection is accessed after the session was closed.
