Hi Forum,

I'm trying to use @MappedSuperclass and @AttributeOverrides in this way:

@MappedSuperclass
public abstract class SuperClass {
@Id protected Long id;
@Basic @Column(name = "aaa") protected String bbb;
}

@Entity @Table(name = "SubTable")
@AttributeOverrides({@AttributeOverride(name = "id", column = @Column(name = "SubID"))}
public class SubClass {
}

By table looks like:
create table SubTable (
id serial,
aaa varchar(255)
);

But I got two problems:
1. AttributeOverride "id" had to add "insertable = false, updatable = false", otherwise, it will give "Repated mapping column in entity: xxxx" error.
2. Column name "aaa" not been used, system will use default column name "bbbb" instead of from @Column annotation. But the column name from AttributeOverrides been used. So, insert query become "insert into SubTable (id, bob) values (?, ?)".

For first, I can add "insertable = false, updatable = false". But what I did wrong with second one?

Thanks a lot
