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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989979#...
