title: no persister for System.Generic.List fluent nhibernate
body: <p>I will insert a list of objects in my database with the following method:</p>
  
  <pre><code>public static void InsertObjekts(List&lt;Objekt&gt; objekts)
  {
       var session = SessionManager.CurrentSession;
       using (var transaction = session.BeginTransaction())
       {
            session.SaveOrUpdate(objekts);
            transaction.Commit();
       }
  }
  </code></pre>
  
  <p>But I get the erroer <code>no persister for System.Generic.List;</code>
  When I iterate over my list to insert every element by own, it only goes in the first iteration, because I have then no session.
  Can someone give me some tips to this topic.</p>
