Hi Team NHibernate,
We have updated NHibernate and NHibernate.Caches.SysCache assemblies to '
*4.0.0.4000*' in our project.
However, now while using second level caching using following code, we are
getting 'ArgumentNullException':
ISQLQuery query = null;
ISession session = ProviderHelper.GetSession();
query = session.CreateSQLQuery("select count(*) as number from
tCSEmailList where email=:Email");
query.SetParameter("Email", email);
query.AddScalar("number", NHibernateUtil.Int32);
query.SetCacheable(true);
query.SetCacheRegion("Type");
var count = query.UniqueResult<int>(); //Getting the
error here
*Error: ArgumentNullException*
Value cannot be null.
Parameter name: includeInTuple
Stack Trace:

includeInTuple, Boolean[] includeInTransform)

IResultTransformer transformer, String[] aliases, Boolean[] includeInTuple)

at
Guru.Data.NHibernate.DataProviders.MessagingData.CSDSIncomingEmailProvider.IsEmailExistsInEmailList(String
email) in c:\******.cs:line 278
However, on removing following second level caching code, the query runs
fine:
query.SetCacheable(true);
query.SetCacheRegion("Type");
Please help us out. This is showstopper for us.
Thanks in advance.
