Dear All:

Using the following code:

@Entity 
@Table(uniqueConstraints=[@UniqueConstraint(columnNames=["account","name"])])
class Friend {
  @Id @GeneratedValue(strategy=GenerationType.AUTO)
  public Long id
  @ManyToOne
  public Account account
  public String href
  public String name
}

I get the following error:

org.hibernate.AnnotationException: Unable to create unique key constraint (account, name) on table Friend: account not found

It seems this has to do with the @ManyToOne constraint, which I imagine actually creates a separate UniqueConstraint???

In any case, if I take this out, there is no complaint about the UniqueConstraint, but there is another error which makes me believe it must be left in.

org.hibernate.MappingException: Could not determine type for: com.mksoft.fbautomate.domain.Account, at table: Friend, for columns: [org.hibernate.mapping.Column(account)]

Any hints how I can create such a desired constraint (i.e., that each combination of account and name occurs only once???)

Thank you!
