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.
