In-memory filter for ModelRef property causes IllegalStateException

[GoogleCodeExporter]

The following in-memory filter for ModelRef property causes
IllegalStateException.

Bbb bbb = new Bbb();
bbb.getHogeRef().setModel(new Hoge());
Datastore.put(bbb);
BbbMeta m = BbbMeta.get();
Datastore.query(Bbb.class)
    .filterInMemory(m.hogeRef.equal(Datastore.createKey("Hoge", 1)))
    .sortInMemory(m.hogeRef.asc).asList();

java.lang.IllegalStateException: The property(hogeRef) of
model(org.slim3.datastore.model.Bbb) is not comparable.
