Hi,
I'm using stable cayenne 3.0.1.
Following the tutorial in vertical inheritance i've been unable to make
vertical inheritance work.
I've modified the tutorial app adding a Programmar as Child of Artist.
It have the following error:
Exception in thread "main" org.apache.cayenne.validation.ValidationException:
[v.3.0.1 Sep 06 2010 15:09:38] Validation failures: Validation failure for
org.apache.cayenne.tutorial.persistent.Programmer.artist: "artist" is required.
Validation failure for

The code for creating a new Programmer in main is:
Programmer picasso = context.newObject(Programmer.class);
picasso.setTipo("P"); // Discriminator added in Artist
picasso.setName("Pablo Picasso");
picasso.setDateOfBirthString("18811025");
Any help will be appreciated.
