Hibernate version:3 beta 1

All
I currently have the following:

public abstract class Party {
...
}

public abstract class Person extends Party{
...
}

public class Employee extends Person {
...
}

These can all be mapped to a single DB table

The problem I have is when I instantiate either a Person or a employee, when persisting to the DB I alsways get the discriminator of 'E'

I know Im doing something wrong but no amount of cludguing around with the mapping file seems to make any difference.

I could change the classes as a last resort or goto table per concrete class etc but Im using a collegues code at the mo to evaluate hibernate 3 so dont really want to change class code if i can help it!!

Thanks in anticipation..

public abstract class Documento{
...
}

public class Proposicao extends Documento{
...
}

public class Veto extends Proposicao{

}


the error message when it executes the following code:



is:

There was no problem to fix really since I was trying to do the mapping without reviewing the code!

Since I had 2 abstract heirachical classes I didnt really need the switch since everyone in effect was an employee

Not quite the same os yours since you dont have 2 abstracts..
Sorry its not more use..
