I have auto-retreive set to false in all my descriptors currently. Reason I do that is because sometimes I am not interested in getting the related objects, I just want to do a select from the table and just get the data back.
However, there are times when I do want to fetch the related objects. So with that, I tried the following code below, but it seems that it's incorrect since my bean still returns a null for the related bean.
final Query query = QueryFactory.newQuery( Category.class, crit );
broker.beginTransaction();
final ObjectReferenceDescriptor ord = new ObjectReferenceDescriptor( broker.getClassDescriptor( Project.class ) );
ord.setCascadeRetrieve( true );
OJB couldn't watch your made changes, 'ord' instance was not integrated. Why you don't use
PB.retrieveAllReferences PB.retrieveReference for these objects you want to know the reference objects?
You can modify the metadata using PB.getDescriptorRepository() and manipulate metadata encapsulated by DescriptorRepository. But made changes are *global*, all threads will see made changes, except if you are using metadata profiles managed by MetadataManager (but this isn't trivial to handle).

final List results = ( List ) broker.getCollectionByQuery( query ); broker.commitTransaction();
I have a foreign key relationship between Category and Project. I was to select categories in this case and also get the Project objects back with it. Project and Category are Interfaces.
