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
