Datatable does not populate object? JSF

Question

I have the following problem:

I have a DataTable which is populated with entities of the type Login that belongs to Usuario as a relationship.

A button called Add Login calls the method addLogin() of Login and a row is added in the table with fields for popular Login.user , Login.pass, Login.mac and Login.Plano. Plano already has to be persisted previously in the database for a list to be displayed with selectOneMenu.

What happens is when you add more than one Login, only the first is populated with the reference of Plano the others accuse an error because the same cannot be null.

Login

@Entity
@Table(uniqueConstraints = @UniqueConstraint(columnNames = "user"))
public class Login implements Autenticavel{

@Id
@GeneratedValue
private Long id;

@ManyToOne
@NotNull
private Usuario usuario;

@ManyToOne
@NotNull
private Plano plano;

@NotNull
private String user;

@NotNull
private String pass;

private String mac;

//GETTERS E SETTERS
}

User

@Entity
@Table(uniqueConstraints = @UniqueConstraint(columnNames = "rg"))
public class Usuario implements AbstractEntity{

@Id
@GeneratedValue
private Long id;

@NotNull
@Size(min = 1, max = 150)
@Pattern(regexp = "[^0-9]*", message = "Não deve conter números")
private String nome;

@NotNull
private String cpfCnpj;

@NotNull
private String rg;

@Temporal(TemporalType.DATE)
private Date dataNascimento;

@OneToOne(cascade = CascadeType.ALL)
private Contato contato;

@OneToOne(cascade = CascadeType.ALL)
private Endereco endereco;

@OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinColumn(name = "usuario_id")
private List<Login> login;

@Enumerated
private TipoPessoa tipoPessoa;

@Enumerated
private TipoPrevilegio previlegio;

@OneToMany(cascade = CascadeType.ALL)
@JoinColumn(name = "usuario_id")
private List<Cobranca> cobranca;

// GETTERS E SETTERS

public void setLogin(List<Login> login) {
    this.login = login;
}

public void addLogin(Login login){
    if(this.login == null)
        this.login = new ArrayList<Login>();
    this.login.add(login);
}

public void addLogin(){
    this.addLogin(new Login(this)); 
}

public void removeLogin(Login login){
    if(this.login.contains(login))
        this.login.remove(login);
}
}

How can I solve this problem?

Answer 1

Problem solved! I discovered that the problem was in the Bootsfaces library, by changing the <b:selectOneMenu /> for <h:selectOneMenu /> everything worked perfectly!

Answer 2

Brother, have you ever tried to adopt an Id? //example @Id @Generatedvalue(Strategy=Generationtype.IDENTITY) // in case you are using a mysql BD.

ps. vc could add your persistence.xml file to improve understanding of its configuration.
