I have 3 levels of classes
a) @MappedSuperclass
public abstract class CmpntObject implements Comparable, Serializable
{
@Column(name = "enabled")
private Boolean enabled = Boolean.TRUE;
}

b)@Entity
@Table(name = "asmnt_item", schema = "public")
@DiscriminatorColumn(name = "question_type_enum", discriminatorType = DiscriminatorType.STRING)
public abstract class Item extends CmpntObject implements Comparable
{
@Column(name = "valid")
private Boolean valid = Boolean.TRUE;
other columns..
}

c) @Entity
@DiscriminatorValue(value = "1")
public class SpecificItem extends AbstractItem
{
}

and when i do the following:

SpecificItem specificItem = new SpecificItem ();
specificItem.setEnabled(false);
specificItem.setValid(false);
session.saveOrUpdate(specificItem);

it persists the valid field (1 level up in the hierarchy) correctly in the database, but does not persist the enabled field (2 levels up in the hierarchy).

Is it a Hibernate issue, wherein it would not persist fields more than 1 level up the hierarchy?
