What's wrong here?

Hello. I'm trying your product but doc is not so good as possible, but i think it's change soon.

So the question is "What's wrong here?" 

 I've got class Post:

public class Post:Entity<int>
{

    private readonly EntityHolder<Member> _owner = new EntityHolder<Member>();

    ...

    public Member Owner
    {
            get { return Get(_owner); }
            set { Set(_owner, value); }
    }

    ... 

} 

And i'm trying to create new object:

Post p = new Post();

p.Owner = Repository.FindOne<Member>(Entity.Attribute("Username") == UserNameTB.Text &&
                                        Entity.Attribute("Password") == PasswordTB.Text);     //It's just testing, so i'm lazy )

 
After executing this i've get NullReferenceException into this line: set { Set(_owner, value); }

Thanks!

P.S.  Sorry for bad english - i'm from Russia )

P.P.S. I've love LightSpeed already )

Hi SynteZZZ,

Could you post your Member class as well? Do you have a reference in the Member class to a collection of posts?

private readonly EntityCollection<Post> _posts = new EntityCollection<Post>();

public EntityCollection<Post> Posts
{
  get { return Get(_posts); }
}

I'm pleased to hear you are enjoying using LightSpeed, I hope this helps.

 No, i haven't. But when i add this lines i've got a LightSpeedException - Could not determine the reverse association of [Member.Posts (IList<Post>)].

Hi SynteZZZ,

Your Post class should look similar to this:

public class Post:Entity<int>
{

    private readonly EntityHolder<Member> _owner = new EntityHolder<Member>();
    private int _ownerId;

    public int OwnerId
    {
      get { return _ownerId; }
      set { Set(ref _ownerId, value, "OwnerId"); }
    }

    public Member Owner
    {
            get { return Get(_owner); }
            set { Set(_owner, value); }
    }

}

Note that you need to ensure you have the foreign key field/property for the OwnerID and the Owner object. I have highlighted the part that I suspect you are missing (make sure you change the names if your field isn't called OwnerID).

If this does not help could you please post your complete Owner and Post classes?

Thanks,
