Hi all,

I have 1 table in DB with 2 column are c1 and c2.
I created 1 entity as follow:
@Entity
@Table(name = "Table1")
public class Table1 implements Serializable {
@Id
@Column(name="c1", nullable = false)
private Long c1;
@Column(name="c2", length = 200)
private String c2;
// getter and setter ...
}

after, I created 1 other entity as follow
@Entity
@NamedNativeQueries({
@NamedNativeQuery(
name = "MyEntityExtend.getData",
query = "select rownum id, Table1.* from Table1",
resultClass = MyEntityExtend.class)
})
public class MyEntityExtend extends Table1 {
public MyEntityExtend() {
}
@Column(name = "ID")
private String id;
// getter abd setter ...
}

But when MyEntityExtend extends Table1 then I cannot merge Table1 object. if there is not any entity extends Table1 then merge Table1 object is OK
Please help me

Duy
