[jboss-user] [EJB 3.0] - Problems with foreign key updates

Hi all,

I have a strange problem with an entity relation. I have a manyToOne relation between an entity called "Address" and and entity called "Country". Address should only use existing Countries. If Country enitity doesn't exists it should throw a kind of ForeignKeyException.

Now my Problem:
If I update the Address with another Country (which is not in den DB yet), the Address entity is only updated in the object instance. The database entry is unchanged. But now I have a new entry in my Country table?? I expected an exception not a new entry.

If I have a Country object and updates my Address, the address row in the db is also not changed?

Here some code fragments:

  | public class Address implements Serializable {
  |     @Id
  |     @Column(name = "id", nullable = false)
  |     private Integer id;
  |     ...
  |     @ManyToOne(fetch=FetchType.LAZY,cascade=CascadeType.ALL)
  |     @JoinColumn(name = "isocodecountry", referencedColumnName = "isocode")
  |     private Country isocodecountry;
  | ...

  | public class Country implements Serializable {
  |     @Id
  |     @Column(name = "isocode", nullable = false, insertable=false, updatable=false)
  |     private String isocode;
  |    ....

My system:

JBoss 4.0.5 GA (from Installer) with SEAM 1.1.0-CR1 on Win XP with a Postgre 8.1.5 DB.

I hope some can help me.
