    There is nothing wrong with an object returned in HOLLOW state from
    relationship (in fact this is expected), however if after calling
    "getName()" an object still remains HOLLOW, this is strange... Could
    you doublecheck that "getName()" is a generated method that looks like
    that:

    public String getName() {
        return (String)readProperty("name");
    }

    and is not overwritten in the subclass?

    There have been no change since 1.0 as far as relationships. You do
    have to have two-way DbRelationships. Also if you have a to-many
    ObjRelationship, some things may not work without a reverse to-one.
    However relationships were made more "lazy" - i.e. if you add set an
    Artist of a Painting, this will not trigger a fetch of all other
    Paintings for this Artist. Also in the nearest future I am planning to
    improve the Modeler UI to make handling of reverse DB relationships
    more transparent.
