JPA - Mapeamento de classe pai com atributo lista

Programação Java
,
#1

É o seguinte pessoal estou com um problema de mapeamento usando JPA.

Estou usando o spring como framework.

Quando chamo o save na minha controller para inserir uma Activity e ActivityFile, funciona tranquilamente. Mas quando depois de inserir vou atualizar qualquer informação do pai ou do filho, como adicionar mais um arquivo, la no banco eu vejo que a FK de activity_file (id_activity) fica nula logo depois da atualização, e aí se perde a referência.

Saquem como estão minhas classes.

Obs: Uma atividade pode ter vários arquivos (ActivityFile)

Activity

@Entity
@SequenceGenerator(initialValue = 1, name = "base_gen", sequenceName = "activity_seq")
@Table(name = "activity")
@AttributeOverrides({ @AttributeOverride(name = "id", column = @Column(name = "id_activity")) })
public class Activity extends GenericEntity {
