I was about to file a bug, but cannot believe no one else had this problem before and maybe I just dont know how to search...

Oracle 9.2.0.4.0, Hibernate 3.2.4.sp1: If an entity with empty string values for its sencondary table attributes is persisted, a row will be inserted into the secondary table even if the empty strings are converted to null by Oracle. If then updated, no row will be expected => trying to insert row again in secondary table => constraint violation.

Does anyone know anything about this problem?

Thanks
