    Problem saving object with empty collection

    Brocha Strous Newbie

      Hello,
      I have an object that inherits from a base class that contains a number of collections - 3 sets and 1 list. The collections are initialized to empty collection objects on construction as follows:

      @Entity
      @Audited
      public abstract class Person{
      
       @ManyToMany
       @JoinTable(
       name = "PeoplesClothes",
       joinColumns = {@JoinColumn(name = "personID")},
       inverseJoinColumns = {@JoinColumn(name = "clothesID")})
       private Set<Clothes> clothes= new HashSet<Clothes>();
      
       @ManyToMany
       @JoinTable(
       name = "PeoplesThings",
       joinColumns = {@JoinColumn(name = "personID")},
       inverseJoinColumns = {@JoinColumn(name = "thingID")})
       private Set<Thing> costSheet = new HashSet<Thing>();
      
       @ManyToMany
       @JoinTable(
       name = "PeoplesCars",
       joinColumns = {@JoinColumn(name = "personID")},
       inverseJoinColumns = {@JoinColumn(name = "carID")})
       private Set<Car> route = new HashSet<Car>();
      
       @OneToMany
       @OrderBy("priority")
       @JoinTable(
       name = "PeoplesFriends",
       joinColumns = {@JoinColumn(name = "personID")},
       inverseJoinColumns = {@JoinColumn(name = "friendID)}
       )
       @org.hibernate.annotations.IndexColumn(name = "friend_PRIORITY")
       private List<Friend> friends= new ArrayList<Friend>();



      When I try to construct the object and leave the collections empty I get the following error (I think when its processing the list collection - but i am not 100% sure):

      What is causing this? I have similar code in other classes and it works fine - I don't see what the difference is between the cases where it works and where it doesn't.

      Thanks,
      Brocha
