NHibernate query against nested class

I'm using NHibernate. I have a class which has a nested type. Is there any way, using NHibernate, to query against the nested type, asides from using a native SQL query开发者_高级运维?

Nested classes are not allowed in HQL currently.

EDIT: The outer class has an IList of nested class instances.

Use a component mapping.

Then, using HQL or Linq to NHibernate, you would simple say something like string hql = "from Store s where s.Employee.Id = 3";

Can't be done currently.
