--------------------------------------------------------

In the version of Hibernate 4.0.1-final auditng over the ManyToOne relation works and data(parent_id) is saved correctly in the audit table, but the generated HBM file looks littel different(see below) as it in version 3.

*The construct of properties in {{<join table}} disappears.*

{code}
...
		<join table="Tree_HIERARCHY_HSTRY">
			<key>
				<column length="255" name="CHILD_ID" precision="19" scale="2"/>
				<column name="REV"/>
			</key>
			<property insert="true" name="parent_id" type="long" update="false">
				<column length="255" name="PARENT_ID" precision="19" scale="2"/>
			</property>
		</join>
...
{code}

> We have a parent-child relationship set up for an entity using a plain link table.  This is annotated with @JoinTable and @AuditJoinTable so there is no entity for the link table itself.  The definition looks something like this...
>  
> @Entity
> @Table(name = "BKG_BKCM_BKG_CMPT")
> @Audited
> public class BookingComponent implements Serializable {
> @ManyToOne(fetch = FetchType.LAZY, optional = true)
> @AuditJoinTable(name = "BKG_BKCMR_REL_AUD", inverseJoinColumns = { @JoinColumn(name = "BKCM_ID_PARENT", nullable = true, updatable = false) })
> @JoinTable(name = "BKG_BKCMR_REL", joinColumns = { @JoinColumn(name = "BKCM_ID_CHILD", nullable = true, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "BKCM_ID_PARENT", nullable = true, updatable = false) })
> private BookingComponent parent;
> @OneToMany(mappedBy = "parent")
> private List<BookingComponent> children;
> }

> We've found two issues.  Firstly, when we try to retrieve a previous revision of these entities (they in turn are held in a collection in a container entity) using List<>.size() Envers seems to be constructing a JPQL query using the link table's table name which isn't valid JPQL resulting in the following exception:
> org.hibernate.hql.ast.QuerySyntaxException: BKG_BKCMR_REL_AUD is not mapped [select new list(ee, e) from BKG_BKCMR_REL_AUD ee, *package-name-omitted*.BookingComponent_AUD e where ee.originalId.BookingComponent_id = e.originalId.id and ee.originalId.children_id = :children_id and e.originalId.rev_id.id <= :revision and ee.originalId.rev_id.id <= :revision and ee.rev_type != :delrevisiontype and e.rev_type != :delrevisiontype and (e.REV_ID_END.id > :revision or e.REV_ID_END is null) and (ee.REV_ID_END.id > :revision or ee.REV_ID_END is null)]

> See attached gjkrupa_envers_problem.zip for a test case that demonstrates this issue.
