I am having a problem using NHibernate.Validator. The class I am
saving has a class property, and it has a string property which is
null. The string property is specified not-null in the class xml
file, and it has a [NotNull] attribute in the class cs file.
I am getting a HibernateException "not-null property references a null
or transient value". I expected to get an InvalidStateException but
it seems like the validator is not getting called before NHibernate
tries to insert it.
Any idea where I'm going wrong?
