[hibernate-users] Out of order cascade persist

Hi there, I'm facing a weird behavior of hibernate. Trying to illustrate: I have three entities, say A, B, and C. In my scheme, A has one B which has one C, which has a reference to the parent A. This is my code: @Entity @Table(name = "ASSOCIADOS") public class Associado implements Serializable { @OneToOne( cascade=CascadeType.ALL ) @JoinColumn( name="idFiliacao" ) private Filiacao filiacao; } @Entity @Table(name = "FILIACOES") public class Filiacao implements Serializable { @OneToOne( cascade=CascadeType.ALL ) @JoinColumn(name="idDependentePai" ) private Dependente pai; } @Entity @Table(name = "DEPENDENTES") public class Dependente implements Serializable { @ManyToOne @JoinColumn( name="idAssociado" ) private Associado titular; } My problem is that when I try to persist a fully configured Associado (with a Filiation that has a Dependente which, in turn, has a reference to the parent Associado) the inserts generated by Hibernate seem to be out of order. I mean, first Hibernate tries to insert the Dependente entity, which has a reference to the primary key of Associado. But, at this point, Associado was not inserted yet. So, I'm getting this error: Caused by: java.sql.BatchUpdateException: Column 'idAssociado' cannot be null And this is the SQL generated by hibernate: insert into DEPENDENTES (nome, nascimento, idParentesco, idAssociado, beneficiarioPeculio, dependentePlanoSaude, id) values ('Nome Qualquer', '', 3, '', 'false', 'false', 6900) Right after the em.persist (I'm using Hibernate JPA) I stop the thread in the debugger and I can see that All the objects got an ID assigned. However, during the commit I'm getting this error. Does anyone have any hint about this? Thanks in advance! Loreno
