louie updated HBX-1075:
-----------------------
Attachment: test-case.zip
Attached is the complete package containing both working single-table inheritance and NOT-WORKING single-table inheritance cases.
Also, the ant build script and build output message are attached in this package. Unzip this package and run ant will generate the same message.
Please let us know if you need more information.

> We are reporting an issue during the database schema generating process using hbm2ddl tools against some entities using single-table inheritance strategy. It works fine for the simple hierarchy entity mappings. It breaks down when we try to modeling the data using single-table inheritance in relational entities. Here is one example:
> The main object:
> @Entity
> @Inheritance(strategy=InheritanceType.SINGLE_TABLE)
> @DiscriminatorValue("S")
> public class MySub1 extends AbstractMySuper {
>
> @ManyToOne(fetch = FetchType.EAGER)
> private MySub1 underlying;
>
> @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy="mysub1")
> private List<ExcludedMySub1> excludedSub1;
>
> @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy="mysub1")
> private List<IncludedMySub1> includedSub1;
>
> ...
> }
> The relationship super-class:
> @Entity
> @Inheritance(strategy=InheritanceType.SINGLE_TABLE)
> @DiscriminatorColumn(name="myType",discriminatorType=DiscriminatorType.STRING, length=1)
> public abstract class AbstractMySub1 {
>
> @Id
> @SequenceGenerator(name = "AbstractMySub1", sequenceName = "AbstractMySub1_id")
> @GeneratedValue(generator = "AbstractMySub1")
> @Column(precision=5)
> private int id;
> @ManyToOne(cascade={CascadeType.PERSIST,CascadeType.MERGE, CascadeType.REFRESH})
> private MySub1 mysub1;
> ...
> }
> The relationship sub-classes:
> @Entity
> @DiscriminatorValue("I")
> public class IncludedMySub1 extends AbstractMySub1 {
> }
> @Entity
> @DiscriminatorValue("E")
> public class ExcludedMySub1 extends AbstractMySub1 {
> }
