NHibernate ISession.Delete

I know it´s a pretty simple question, but what happens when one calls ISession.Delete with a transient entity? I suspect that an exception is thrown, but could not find anything in the documentation.

It will NOT throw any exception and it will NOT make any db call.

here is the unit test which pass:

    [Test]
    public void TestDeletionOnTransientObject()
    {
        NormalSalesFlowActivity normalSalesFlowActivity =
            Factories.SalesFlowActivityFactory.CreateNormalSalesFlowActivities(null, 
            opt => opt.NoOfEntities(1)).First();

        Assert.That(normalSalesFlowActivity.Id, Is.EqualTo(0));

        Session.Delete(normalSalesFlowActivity);
    }

First parameter of CreateNormalSalesFlowActivies is the NH Session, if it is supplied when entity is attached to Session and by default is stored to db.

Based on my experience, an exception will NOT be thrown.
