[eclipselink-users] AttributeGroup, EntityManager.load(...) with Relations to Abstract Superclass
|
Hello,
I have a question about fetching Relations with the
EntityManager.load(...)-functionality.
Following Example:
I have an abstract superclass "AbstractPerson" and two concrete
implementations "LargePerson", "SmallPerson". Additional to the fields and
relations defined in the "AbstractPerson" the concrete classes have some
relations on their own. All classes mapped as entities with table-per-class.
Now I have an entity "Example" with a oneToOne Mapping to a property
"person" of Type "AbstractPerson".
What I want to do now is:
* load some Entity of Type example.
* Define a AttributeGroup which contains the oneToOne relation "person" and
relations of the concrete-implemented-entities of AbstractPerson.
* execute JpaEntityManager.load(entities,attributeGroup)
* as result I expect the path example.person.concreteRelationOfTypeOfPerson
is fetched.
All I achieved so far is the path example.person is fetched.
What can I do?
best regards
Stefan
