[JBoss-user] [JBoss Seam] - Entities with one/many_to_many relationships and SEAM

[trouby <do-...@jb...>]

Hey guys,

I was wondering,

Assuming I have an entity with one_to_many relationship, i.e:

  | class X {
  |   String name;
  |   Collection<Y> yList;
  | 
  |    @Column(name="NAME")
  |    public long getName() {
  |        return name;
  |    }
  |     
  |     public void setName(String name) {
  |         this.name = name;
  |     }
  | 
  | 
  |   @OneToMany(mappedBy="x")
  |   public Collection<Y> getyList() {
  |       return yList;
  |   }
  | 
  |   public setYList(Collection<Y> yList) {
  |     this.yList = yList;
  |   }
  | }
  | 


Assuming I'd like to build some web GUI for class X, but except simple fields (such as name) I'd also like to set multiple Y entities to the collection  of the X class through a WEB interface,

Does Seam supports this easily? or i'll have to create a 'multiple selectbox' and pass IDs of Y entities, load the Y entities and set them into the collection by myself?

Thanks a lot,

Asaf.
