Hi.

I am trying to update data in SQL server 2005 database but i am getting error in this function as follows:

public T GetById(IdT id, bool shouldLock)
{
T entity;
//object id1 = (Object)id;
if (shouldLock)
{

entity = (T)NHibernateSession.Load(persitentType, id, LockMode.Upgrade);
}
else
{
entity = (T)NHibernateSession.Load(persitentType, id);
}
return entity;


}
and in the following line :

entity = (T)NHibernateSession.Load(persitentType, id,LockMode.Upgrade);

as Identifer Type mismatch for Id.

What kind of type is IdT ? Can you post a mapping file ?
