Check your transaction demarcation.  Just because you exit a method does NOT automatically mean your entity manager flushes the data to the DB.

If you exit a method that also exits out of your transaction, THEN it will flush.  But if you exit a method that was called with an already started transaction (e.g. tx type== SUPPORTS or an intra-bean call) then it won't necessarily do anything.

For example, if you call A.method1 which calls A.method2, exiting A.method2 probably won't do anything special (it could, if you want - see REQUIRES_NEW semantics).  Exiting A.method1 won't do anything special either, unless the transaction boundary stops at A.method1 (@TransactionType is REQUIRES for example and it was called outside of any tx)
