-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 the simple answer is yes. However I don't think what you have in mind is covered under that answer. your problem of finding an entity has nothing to do with a database. Think of the database only as a storage medium. the error your getting is from the entity engine. it would be wise to re-visit the tutorial and the links on the videos.
