Hibernate version: 3.0

The generated SQL (show_sql=true):

Debug level Hibernate log excerpt:

I'm have this:

Code:

paramSupplier = (Supplier) s.load(Supplier.class, request.getParameter("supplierId"));

supplierId field is always greater than 0 in the database. That's why when i have that piece of code trying to load a supplierId = 0, i expect paramSupplier to be null, but that doesn't happen. Something is returned, but it's not null. If i try to read any of the properties os the non-null object, an exception is thrown.

Why is it no null? Is this the way Hibernate is reallly supposed to work?

Thanks to all
Eduardo
