[Hibernate-issues] [Hibernate-JIRA] Created: (ANN-360) Many-To-Many relationship with attributes on relationship

[Peter M. (JIRA) <no...@at...>]

Many-To-Many relationship with attributes on relationship
---------------------------------------------------------

         Key: ANN-360
         URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-360
     Project: Hibernate Annotations
        Type: Bug

  Components: binder  
    Versions: 3.2.0.cr1    
 Environment: Hibernate 3.2.0cr2, HibernateAnnotations 3.2.0cr1, HQL
    Reporter: Peter Muir
    Priority: Critical


Use a composite foreign key on an entity (A) to model an many to many entity(B)-entity(C) relationship with attributes on the relationship.  

This is supported using hibernate mapping files.

See http://forum.hibernate.org/viewtopic.php?t=958753 for more discussion.

[Hibernate-issues] [Hibernate-JIRA] Updated: (ANN-360) Many-To-Many relationship with attributes on relationship

[Peter M. (JIRA) <no...@at...>]

     [ http://opensource.atlassian.com/projects/hibernate/browse/ANN-360?page=all ]

Peter Muir updated ANN-360:
---------------------------

    Attachment: manytomanywithattributes.zip

Attached is a runnable test.  It supports mapping via hibernate mapping file (for which the tests pass) and via annotations (for which the tests fail).  The correct semantics may not have been used for the annotation version (the annotations don't accept my mappedBy attribute) but the semantics (for the annotation version) have been kept as close as possible to those used for the hibernate mapping. If the hibernate mapping file can be mapped in HibernateAnnotations (3.2.0cr1) using different semantics then I apologise, this is not a bug!

Peter Muir commented on ANN-360:
--------------------------------

Also, I haved tested this with mappedBy="id.productId" as well as plain mappedBy="productId".  Neither work.

[Hibernate-issues] [Hibernate-JIRA] Resolved: (ANN-360) Many-To-Many relationship with attributes on relationship

[Emmanuel B. (JIRA) <no...@at...>]

     [ http://opensource.atlassian.com/projects/hibernate/browse/ANN-360?page=all ]
     
Emmanuel Bernard resolved ANN-360:
----------------------------------

    Resolution: Rejected

This is actually a misuse of mappedBy

should be
@OneToMany(mappedBy="chargeType")
private List<Charge> charges;

@OneToMany(mappedBy="product")
private List<Charge> charges;
