I'm using the JPA Discriminator annotation with single table inheritance strategy and a Hibernate ORM implementation to handle the different user types in my application. When an unknown discriminator value is present in the data Hibernate throws an exception like this:
Caused by: org.springframework.orm.hibernate3.HibernateObjectRetrievalFailureException: Object with id: 3867 was not of the specified subclass: com.example.persistence.model.BaseUser (Discriminator: report); nested exception is org.hibernate.WrongClassException: Object with id: 3867 was not of the specified subclass: com.example.persistence.model.BaseUser (Discriminator: report)
Is there a JPA way/annotation to ignore unknown discriminator values?
Thank you,
Tom
