I have a situation where I have a one-to-many:
Document 1 ---> m DocumentVersion.
The document version has a composite-id.
| <class name="com.eLynx.Core.Database.Entity.DocumentVersion"
| table="DocumentVersion"
| lazy="false">
|
| <composite-id >
| <key-many-to-one name="document"
| column="ContentId"
| class="com.eLynx.Core.Database.Entity.Document"/>
|
| <key-property name="version" column="Version" type="int"/>
| <key-property name="mimeType" column="MimeType" type="string"/>
| </composite-id>
|
| <timestamp name="CreationDate" source="db" />
|
| <property name="CSFileId" type="long">
| <column name="CSFileId" not-null="true"/>
| </property>
|
| </class>
The Document class is a subclass:
| <!-- Document subclass definition -->
| <subclass name="com.eLynx.Core.Database.Entity.Document"
| discriminator-value="D">
|
| <list name="DocumentVersions"
| table="DocumentVersion"
| inverse="true"
| cascade="all">
|
| <key column="ContentId"/>
| <index column="version"/>
| <one-to-many
class="com.eLynx.Core.Database.Entity.DocumentVersion"/
| </list>
|
| </subclass>
I have test data where a document has one version. When I do the load from:
| Document root = (Document) session.load (Document.class, 146L);
| List<DocumentVersion> versions = root.getDocumentVersions();
|
then examine the list in the debugger I see:
| [null, [EMAIL PROTECTED]
I cannot, for the life of me, figure out why I have that null in the first
position. Anyone have any ideas? Thanks in advance.
