Hello I am using tinyint(1) in MySQL DB and use Mygeneration to generate NHibernate Contribute 0.8.4 table mapping.
Here is the mapping column of nhibernate for tinyint(1)
...
<property column="getNews" type="Byte" name="GetNews" />
...

After I have successful generate the source code files and nhibernate mapping files then I tried to build the generated code. It said error of "value.Length" because byte in .net do not have "Length" property. So I comment out the lines of length checking then it looks like
...
public byte GetNews
{
get { return m_getnews; }
set
{
// if( value.Length > 0)
// throw new ArgumentOutOfRangeException("Invalid value for GetNews", value, value.ToString());

m_isChanged |= (m_getnews != value); m_getnews = value;
}

}
...


I try to run the code using
...
string mappingAssembly = "Aibiz.EmailReminderService.Data";

// Create NHibernate configuration
Configuration cfg = new Configuration();

// Add mapping assembly to configuration
// Mapping assembly has the Entities and mappings
cfg.AddAssembly(mappingAssembly);

// Create a session factory
ISessionFactory factory = cfg.BuildSessionFactory();

ISession session = null;

try
{
// Create a sesson
session = factory.OpenSession();

ICriteria criteria = session.CreateCriteria(typeof(Hostings));
SimpleExpression expression = Expression.Ge("HostStop","2004-09-10");
criteria.Add(expression);

IList hostings = criteria.List();//session.Find("from Hostings where HostStop like ?", "2005-09-10", NHibernateUtil.String);

foreach (Domains domain in hostings)
{
log.Debug(domain.Domainid);
}
}
catch (Exception ex)
{
log.Error(ex);
}
finally
{
session.Close();
}

...

Then error occurs at line "cfg.AddAssembly(mappingAssembly);" and the stack trace says
...

I think the problem is data length mapping checking between xml and mysql data type because "byte" do not have "Length". But how to fix this?
