    Problems with foreign key updates

    Marco Huber Newbie

      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.

      Regards
      Marco
