> I use NHibernate 1.2.0 Beta1 with MySQL 5.0

> "System.NullReferenceException: Object reference not set to an instance of an object"
> I get this ERROR when I try to load Entity Class from a table's column contains NULL value, column's type is Varchar;  however if the colums has any value , the entity class can be loaded without ERROR!
> The entity class that i loaded is a single class which no assiciation to anothor class.
> So I think the ERROR is BUG.
