Hi,

I'm trying to solve some of my problems when updating composite-id'ed objects... I've implemented my little interceptor (madmax), which just test a value to decide if the object isUnsaved or not.

I get to the isUnsaved, and it seems to work fine, returning false when the object has been saved before... but...seems like my saveOrUpdate is not doing anything with my object.

Hibernates log says:

Code:

  - saveOrUpdate() previously saved instance
  - updating [com.previsora.data.hibernate.Beneficiario#com.previsora.data.hibernate.BeneficiarioPK@5b46]
  - calling onUpdate()
  - flushing session
  - Flushing entities and processing referenced collections
  - Processing unreferenced collections
  - Scheduling collection removes/(re)creates/updates
  - Flushed: 0 insertions, 0 updates, 0 deletions to 1 objects
  - Flushed: 0 (re)creations, 0 updates, 0 removals to 0 collections
  - listing entities:
  - com.previsora.data.hibernate.Beneficiario{idioma=null, apellidos=null, anyonac=null, estadoCivil=null, idProfesion=null, PKBeneficiario=BeneficiarioPK{numAsegurado=2, numSolicitud=19}, mesnac=null, telfMovilProfesional=null, sexo=null, mail=null, dianac=null, dni=null, permisoResidencia=null, nombre=null, telfMovil=699065269, falsa=19, nacionalidad=null}
  - executing flush
  - post flush

Is Hibernate really trying to update my object...? I think it should, because of the first lines of the log... but I get no exception, and I get no change in the data neither.
The phone above is the changed field, and it doesn't get updated in the database.

What am I doing soooo wrong?

TIA,

What does Lifecycle.onUpdate() return?

it returns false, and id does return the value without throwing the exception.

Code:

  public boolean onUpdate(Session session) throws CallbackException {
    return false;
  }

Hi,

seems like I finally got it... but this does not necessarily means I undestand it :-(

Debugging through Hibernate's code, seemd like my object would not be updated, because it was not considerated "dirty enough".

The test I was running is like:

Code:

    IBeneficiario b3 = mgr.newBeneficiario();
    b3.setSolicitud(sol);
    b3.setNumAsegurado(new Integer(3));
    b3.setTelfMovil(new Long(600066066));
    mgr.save(b3);
    mgr.close();

    IPersistenceManager mgr11=Previsora.getManager();
    b2.setTelfMovil(new Long(699065269));
    mgr11.save(b2);
    mgr11.close();

So the field setTelfMovil has been modified, so I would expect hibernate to automagically infere my object was dirty.

To force this, I'm now checking in the findDirty method if the passed object is one of my IBeneficiario implementation's and if so, I will always considere it "dirty".

This does not sound too performance aware to me, and neither too elegant, but it's the only workaround I found so far.
Has anybody else got any better solution?

Also... a doubt... why is Interceptor.findDirty returning an array of ints??
Is it supposed to be kind of a flag/mask to decide which property has been changed? Seems like it's not checked in the calling code, till now?
