anonymous wrote : Some of my coworkers have reported similar behaviour of a sporadic nature...simple calls to EntityManager.find(Class,id) return null when the object is clearly in the DB. They've also stated that using EntityManager.createQuery("SELECT obj FROM ClassName obj WHERE obj.id=?") will sometimes return the object immediately after the finder fails. I tried getting the object by using a createQuery() myself and still found I was returned a null value. The behaviour I have seen with the find() function has not been sporadic but consistently failing, when the PK was a string. entityManager.find(Language.class, "en "); Ah, yes. This rings a bell...I seem to recall an issue with Oracle padding out char columns with spaces. I will change the column to a varchar and retest. Thanks for the thoughts everyone.
