Hello,

In my model I have a series of classes that extend an abstract class named Resource and I want those classes to have mutually exclusive id's (the id being their primary key) because I want to be able to reference any Resource by unique id. I created a sequence in the database (PostgreSQL 8) named "SEQUENCE_GLOBAL_RESOURCE_ID". My code like this:





Example of entity which extends Resource:





Now if I retrieve an Organization, the instance I get has all the fields correct (as in the database) except for id which is 0! Does anyone have any idea why this is happening?

Thanks.
