Hello!
I have a @PersistenceCapable _abstract_ class ParentEntity, and a
PersistenceCapable derived class ChildEntity. The Parent class has a
field "s_name".
I created and saved a ChildEntity with s_name "foo".
When I do
query = pm.newQuery( ParentEntity.class );
query.setFilter( "s_name == s" );
query.declareParameters("String s");
@SuppressWarnings("unchecked")
List<ParentEntity> results =
(List<ParentEntity>) query.execute("foo");
I receive an empty list. When I do
query = pm.newQuery( ChildEntity.class );
query.setFilter( "s_name == s" );
query.declareParameters("String s");
@SuppressWarnings("unchecked")
List<ChildEntity> results =
(List<ChildEntity>) query.execute("foo");
I get a list with my entity.
Question: is this "by design"? Is there a way to query for
ParentEntities and receive all entities (potentially of different
kinds) of derived classes that match the filter? If not, then what is
the use case of the currently supported flavor of inheritance
(complete-table/subclass-table)?
Thanks,
MG
