I have a table structure that is five levels deep, all tables are lazy loaded. But when I sometimes access an object from the first table, I want all underlying data as well. I can use the NhibernateUtil.Initialize() method, but that only loads the second level of data (i.e. the level right under the first level), not all levels.

Do I have to implement an initialize-with-cascade method on my own, or can this be done with NHibernate?
