BTW...what's the *expected* requirement for creating/updating objects with lazy-loaded independent objects? Do I need to load any direct lazy-loaded, independent objects? For example would this work? If not why? What if Property1 defined a direct lazy-loaded, independent object (i.e. Property3)?
db.begin(); Property1 propertyOne = db.load(Property1.class, prop1Id); Property2 propertyTwo = db.load(Property2.class, prop2Id); db.commit(); Parent parent = new Parent(); parent.setProperty1(propertyOne); parent.setProperty2(propertyTwo); db.begin(); db.create(parent); db.commit(); Do I have to load all direct independent objects?
