[Middlegen-user] Issue with airline demo and hibernate

[Darin Buck]

Using:
middlegen-2.1
java 1.4.2_08

I changed the sample app to use hibernate instead of cmp20, which
results in a broken build:

Looking at the first error in the code, it appears that the generated
value object isn't using the generated composite key object:

here is what is generated:

from middlegen-2.1/samples/build/gen-src/airline/adapter/TranslatorUtil.java:

/**
* Copy data from a airline.web.struts.ReservationForm value object
into a airline.hibernate.Reservation object.
*
* @param reservationPersistence The
airline.hibernate.Reservation object into which the data is to be
copied.
* @param reservationForm The
airline.web.struts.ReservationForm value object containing the data to
be copied.
*/
protected static void
copyVoToPersistence(airline.hibernate.Reservation
reservationPersistence, airline.web.struts.ReservationForm
reservationForm) throws Exception {
// Persistence layer specific implementation
reservationPersistence.setReservationId(reservationForm.getReservationId());
reservationPersistence.setPersonIdFk(reservationForm.getPersonIdFk());
reservationPersistence.setFlightIdFk(reservationForm.getFlightIdFk());
reservationPersistence.setRegistrationUtc(reservationForm.getRegistrationUtc());

reservationPersistence.setComment(reservationForm.getComment());
}

Instead it should probably look more like:

protected static void
copyVoToPersistence(airline.hibernate.Reservation
reservationPersistence, airline.web.struts.ReservationForm
reservationForm) throws Exception{
// Persistence layer specific implementation
reservationPersistence.setComp_id(new
airline.hibernate.ReservationPK(reservationForm.getReservationId(),
reservationForm.getPersonIdFk(), reservationForm.getFlightIdFk()));
reservationPersistence.setRegistrationUtc(reservationForm.getRegistrationUtc());

reservationPersistence.setComment(reservationForm.getComment());
}

The same issue exists with the "copyPersistenceToVo" method.

Hopefully there is just some sort of configuration that I messed up.
The cmp20 version worked fine, though.

Thanks for reading this far...

I had the same issue. Could not figure out how to fix it yet.
