seguinte, o objeto Debito possui uma lista de objetos MeioDepositoOrigemDebito, e ao listar (mostrar na tela) cada objeto Debito, ele eh exibido a mesma quantidade de vezes que o numero de objetos na lista de MeioDepositoOrigemDebito!!
no banco existe apenas um registro de cada Debito… e na tela mostra desse jeito…
a duplicaçao ocorre ao recuperar a lista de debitos, ou seja, a partir do seguinte método o objeto Debito já eh retornado duplicado na lista:public List<Debito> listarPorCenario(Long id){
return this.session.createCriteria(Debito.class).add(Restrictions.eq("idCenario", id)).list();
}
mas essa mesma estrutura do método eh usado para recuperar outras listas e nao duplica os outros objetos dessas listas…
Cara, vou postar a minha classe Debito pra vc dar uma olhada:[code]@Entity
public class Debito extends Valor implements Serializable {
@NotNull(message="A operaçao necessaria deve ser informada!")
private Boolean operacaoNecessaria;
@ManyToOne
@NotNull(message="O meio de debito deve ser informado!")
private MeioDebito meioDebito;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, orphanRemoval = false)
@NotNull(message="O meio de deposito de origem do debito deve ser informado!")
private List<MeioDepositoOrigemDebito> listaMeioDepositoOrigemDebito;
private Boolean snEntrada;
public Debito(){
}
//getters and setters
o EAGER eh pra carregar a lista quando o Debito for carregado, certo? Se sim, entao nao preciso disso…
o cascade=ALL precisa pq essa lista vai ser persistida no mesmo momento em que o Debito for persistido, e a lista sera excluida quando o Debito for excluido…
eu fiz como vc disse Lucas, tirei o EAGER e o cascade.ALL@OneToMany(cascade = {CascadeType.PERSIST,CascadeType.REMOVE}, orphanRemoval = false)
@NotNull(message="O meio de deposito de origem do debito deve ser informado!")
private List<MeioDepositoOrigemDebito> listaMeioDepositoOrigemDebito;
mas deu esse erro agora:19/10/2012 18:30:05 org.apache.catalina.core.StandardWrapperValve invoke

Lucas, eu fiz assim e funcionou certinho:@OneToMany(cascade = CascadeType.ALL, orphanRemoval = false)
@NotNull(message="O meio de deposito de origem do debito deve ser informado!")
private List<MeioDepositoOrigemDebito> listaMeioDepositoOrigemDebito;
apenas substitui o cascade = {CascadeType.PERSIST,CascadeType.REMOVE} por cascade = CascadeType.ALL…
