I have been using a datamodel with reservation<-> voucher for some time.
Most of the time a reservation has to be created, sometimes a voucher. Most of the vouchers are already in the database.The way I save the data is to create a reservation, select a voucher, and then add the voucher to the reservation, in such a way:
defaultEC().insertObject(mySess().selectedReservation() );
mySess
().selectedReservation().setVoucherRelationship( mySess().voucher() );
After that, I add the reservation to the voucher:mySess ().selectedReservation().setVoucherRelationship( mySess().voucher() );
and save the data:
try {
defaultEC().saveChanges();
defaultEC
().refreshObject(mySess().selectedReservation().trainingdata());
} catch (Exception e) {
defaultEC().revert();
etc...
That has been working fine for ages. Now I added an extra relationship
to the voucher in the BusinessLogic, (the voucher are now linked to a
specific training), reran EOGenerate, but now I am getting errors that
the voucher can not be saved:

I noticed that reservation (the relationship to the reservation that has just been inserted) is "null" in the ERXValidationException, but I am not sure if that is a problem.
If I remove the linemySess ().selectedReservation().setVoucherRelationship( mySess().voucher() );
Everything is fine, apart of coure that there is no relation from the voucher to the reservation, just from the reservation to the voucher.
Have I done something wrong for ages, that now had suddenly reared its head? (Using the latest Wonder as of last night, despite the warning not to do cvs commit. I thought cvs update would be OK).
