I get error
org.hibernate.HibernateException: Encountered problem trying to hydrate identifier for entity [SingleTableEntityPersister(biz.mbisoftware.fn.ejb.entity.MbiTermi)]
with this stack trace as the cause:
Caused by: java.lang.IllegalArgumentException: Unknown ordinal value [40] for enum class [biz.mbisoftware.fn.datatypes.DeliveryDateType]

In other cases, where a "normal" field has an enum datatype with @Convert/@Converter class this work just fine.
But in this case the entity class has a combined primary class of three fields, one of them is of enum datatype (DeliveryDateType).
Adding @Convert( converter = DeliveryDateType.Converter.class ) also to the PK field did not help.
@Convert/@Converter class seem not to be taken into account here, as Hibernate is searching for an enum with ordinal value of 40.

@Entity
@IdClass( value = MbiTermi.PK.class )
@Table( name = "mbi_termi" )
public class MbiTermi implements Serializable
{
....
@Id
@Column( name = "termin_art", nullable = false )
@Convert( converter = DeliveryDateType.Converter.class )
private DeliveryDateType terminArt;
...
public static class PK implements Serializable
{
...
@Convert( converter = DeliveryDateType.Converter.class )
private DeliveryDateType terminArt;
...
}
}
What's the right way which is working?
Or may this be a bug in ORM 4.3.0?

P.S.: with or without @Convert in PK class makes no difference.
Also changing Converter to "autoApply = true" and removing all @Convert annotations gives the same problem.
