Question

I call this function on my objects when they need to be initialized again:

public virtual void Initialize()
{
    if (!HibernateSessionManager.Instance.GetSession().Contains(this)) {

        try
        {
            HibernateSessionManager.Instance.GetSession()
                             .Lock(this, NHibernate.LockMode.None);
        }
        catch (NonUniqueObjectException e) { }
    }
}

I thought I can prevent initializing something twice with checking Contains(this), but it happens sometimes that Lock(this, NHibernate.LockMode.None) throws a NonUniqueObjectException. So far I ignore it because it works, but I’d like to know the reason and a better way to Lock my objects.

the problem was a completely different – contains checks for equality by reference if I don’t override Equals(). Now it works with the code from my question!

    public override bool Equals(object obj)
    {
        if (this == obj) { 

            return true;
        } 

        if (GetType() != obj.GetType()) {

            return false;
        }

        if (Id != ((BaseObject)obj).Id)
        {

            return false;
        }

        return true;
    }
