I'm using Cayenne 3.2M1 and Postgres 9.0.1 to create a database. Right now I'm having problems with the primary key generation of Cayenne since I have tables with more than one primary key and as far as I've read Cayenne cant generate more that one primary key per table. So I want the Postgres to do that work. I have this table:
CREATE TABLE telefonocliente
(
cod_cliente integer NOT NULL DEFAULT currval('cliente_serial'::regclass),
cod_telefono integer NOT NULL DEFAULT nextval('telefonocliente_serial'::regclass),
fijo integer,
CONSTRAINT telefonocliente_pkey PRIMARY KEY (cod_cliente, cod_telefono)
)
WITH (
OIDS=FALSE
);
TelefonoCliente telefono = context.newObject(TelefonoCliente.class);
telefono.setFijo(4999000);
context.commitChanges();
and this is the error I get:
INFO: --- transaction started.

I've been trying the suggestions on Cayenne tutorial "generated columns", "primary key support" but I seems to always get some error.
INFO: SELECT nextval('pk_telefonocliente')
Exception in thread "main" org.apache.cayenne.CayenneRuntimeException: [v.3.2M1 Jul 07 2013 16:23:58] Primary Key autogeneration only works for a single attribute.
I want to know how to solve this. Thanks in advance
