This is probably a simple question to answer but I just can't figure it out.

I have a "Company" class with a many-to-one to "Address" which has a many to one to a composite id in "City". When I load a "Company" it loads the "Address", but if I call any property of "Address" I get the error:

{"could not load an entity: [IDI.Domain.Entities.Address#2213][SQL: SELECT address0_.AddressId as AddressId13_0_, address0_.Street as Street13_0_, address0_.floor as floor13_0_, address0_.room as room13_0_, address0_.postalcode as postalcode13_0_, address0_.CountryCode as CountryC6_13_0_, address0_.CityName as CityName13_0_ FROM Address address0_ WHERE address0_.AddressId=?]"}

The inner exception is:

{"Invalid column name 'CountryCode'.\r\nInvalid column name 'CityName'."}

What I don't understand is that I can run the query in sql server 2005 and it works, furthermore both those columns exist in the address table.

Here are my HBMs:

Here is my code that calls the Company:

IList<BursaUser> user;
            if(String.IsNullOrEmpty(email) && String.IsNullOrEmpty(company))
                return null;
            ICriteria criteria = Session.CreateCriteria(typeof (BursaUser), "user").CreateCriteria("Company", "comp");
            if(String.IsNullOrEmpty(email) || String.IsNullOrEmpty(company) )
            {
                user = String.IsNullOrEmpty(email) ? 
                    criteria.Add(Expression.Eq("comp.Name", company)).List<BursaUser>() 
                    : criteria.Add(Expression.Eq("user.Email", email)).List<BursaUser>();

            }

And finally here is where i get the error:

"user" was already initialized with the code above:

 if (user.Company.Address.City == null)
                    user.Company.Address.City = new City();

Thanks.
