Many To Many with attribute

[d34d_d3v1l]

Hi Guys...

I´m using spring data and I can´t persist my new entity with there relationships...
I also can´t update .. Some error, but one thing at the time..

I have the following mapping:

[code=java]

@Table(name = "com_prospecto")
@Entity
public class Prospecto {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;

@ManyToMany
@JoinTable(name = "com_historico_acoes", joinColumns = @JoinColumn(name = "id_prospecto"), inverseJoinColumns = @JoinColumn(name = "id_acao"))
private List<Acao> acoes;

@OneToMany(fetch = FetchType.EAGER, mappedBy = "prospecto")
private List<ProspectoCampo> prospectoCampos;

[/code]

And I have:

[code=java]

@Table(name = "com_prospecto_campo")
@Entity
@IdClass(ProspectoCampo.class)
public class ProspectoCampo implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@ManyToOne
@JoinColumn(name = "id_prospecto")
private Prospecto prospecto;

@Id
@ManyToOne
@JoinColumn(name = "id_campo")
private Campo campo;

private String valor;
[/code]

And I´m trying to save like this:

[code=java]
public String salvar(){
Prospecto prospecto = new Prospecto();
List<ProspectoCampo> prospectoCampos = new ArrayList<ProspectoCampo>();
List<Acao> prospectoAcoes = new ArrayList<Acao>();

for(ProspectoHelper hp : ProspectoHelper.extrairDadoDoModelo(dynaFormModelA tual)){
ProspectoCampo pc = new ProspectoCampo();
pc.setCampo(campoService.findOne(hp.getPropertyFil ter().getCampo().getId()));
pc.setValor(hp.getPropertyFilter().getValue().toSt ring());
pc.setProspecto(prospecto);
prospectoCampos.add(pc);
}

prospecto.setProspectoCampos(prospectoCampos);
prospecto.setAcoes(prospectoAcoes);

try{
prospectoService.save(prospecto);
}catch(Exception e){
log.error("Erro ao salvar Prospecto!", e);
messageUtil.sendErrorMessageToUser("global.error", "global.insert.error", e.getMessage());
return null;
}

return getRadarPath();
}
[/code]

I´m using Spring Data!

What happends Spring Data persist the "Prospecto" entity, but doesn´t persist its relationship (ProspectoCampos and Acoes).

Am I doing something wrong?
thanks!
