Whenever you put an object in a DataItem, NHibernate figures out how to save this 'Value' entity using what is called an Any mapping. As part of this Any mapping mechanism, NHibernate stores the (CLR, .NET) type of the object in a column in the database as fully qualified string. Also sometimes we map types directly, for whatever reasonexample ValueType of a dataitem.
This is all fine, until you rename a class..
