    Unidirectional ManyToMany empty collection

    Fabio Ospitia Newbie

      Hi

      I have a problem with a Entity with 3 unidirectional ManyToMany collections. The entity is:

      public class Media implements Serializable, Comparable<Media> {
      ..
      
       @javax.persistence.ManyToMany( cascade = { javax.persistence.CascadeType.PERSIST, javax.persistence.CascadeType.MERGE } )
       @javax.persistence.JoinTable(name = "nv_media_category", joinColumns = @javax.persistence.JoinColumn(name = "media_id", nullable = false), inverseJoinColumns = @javax.persistence.JoinColumn(name = "category_id", nullable = false))
       private Set<Category> categories = new HashSet<Category>();
       @javax.persistence.ManyToMany( cascade = { javax.persistence.CascadeType.PERSIST, javax.persistence.CascadeType.MERGE } )
       @javax.persistence.JoinTable(name = "nv_media_content", joinColumns = @javax.persistence.JoinColumn(name = "media_id", nullable = false), inverseJoinColumns = @javax.persistence.JoinColumn(name = "content_id", nullable = false))
       private Set<Content> contents = new HashSet<Content>();
       @javax.persistence.ManyToMany( cascade = { javax.persistence.CascadeType.PERSIST, javax.persistence.CascadeType.MERGE } )
       @javax.persistence.JoinTable(name = "nv_media_comment", joinColumns = @javax.persistence.JoinColumn(name = "media_id", nullable = false), inverseJoinColumns = @javax.persistence.JoinColumn(name = "comment_id", nullable = false))
       private Set<Comment> comments = new HashSet<Comment>();
      
      ..
      
      }
      


      The problem is when create a new Media Entity and the collection comments is empty the follow code give a exception in the emanager.flush();

      
       try {
       emanager.persist(media);
       emanager.flush();
       } catch (Exception ex) {
       throw new MediaDaoException(ex);
       }
      
      


      the exception:
