Repeated column in mapping for entity in composite id
-----------------------------------------------------

                 Key: HHH-4582
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4582
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.1
         Environment: Hibernate 3.3.1
            Reporter: Franck Bisti
            Priority: Minor
         Attachments: PersistentClass.java

I have a composite-id with 2 manytoone. The two manytoone are composed by 3 columns each. They share 2 columns. 

@Embeddable
public class FooBarId implements Serializable {
    @ManyToOne()
    @JoinColumns({
        @JoinColumn(name="FOO_BAR1", referencedColumnName="FOO_BAR1",nullable=false, updatable=true, insertable=true),
        @JoinColumn(name="FOO_BAR2", referencedColumnName="FOO_BAR2",nullable=false, updatable=true, insertable=true),
        @JoinColumn(name="FOO_ID", referencedColumnName="ID",nullable=false, updatable=true, insertable=true)
    })
    private Foo foo;
        
    /** Attribute*/
    @ManyToOne()
    @JoinColumns({
        @JoinColumn(name="FOO_BAR1", referencedColumnName="FOO_BAR1",nullable=false, updatable=false, insertable=false),
        @JoinColumn(name="FOO_BAR2", referencedColumnName="FOO_BAR2",nullable=false, updatable=false, insertable=false),
        @JoinColumn(name="BAR_ID", referencedColumnName="ID",nullable=false, updatable=false, insertable=false)
    })
    private Bar bar;

Exception :
Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.test.FooBar column: FOO_BAR2 (should be mapped with insert="false" update="false")
	at org.hibernate.mapping.PersistentClass.checkColumnDuplication(PersistentClass.java:670)
	at org.hibernate.mapping.PersistentClass.checkColumnDuplication(PersistentClass.java:711)
	at org.hibernate.mapping.PersistentClass.validate(PersistentClass.java:468)
	at org.hibernate.mapping.RootClass.validate(RootClass.java:215)
	at org.hibernate.cfg.Configuration.validate(Configuration.java:1135)

	at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:854)
	at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669)

I have the "Repeated column in mapping" exception because Hibernate doesn't use the insertable and updtable property in the PersistentClass.checkColumnDuplication for composite-id.

I have modified the PersistentClass.checkColumnDuplication() by use of getColumnUpdateability code and it seems to works fine (see attached file)

I don't know if that can help
