Thanks a lot for your posts. I use your method BurrowFramework
().GetSessionByName(string PersitenceName);
But It does'nt work if the Session is directly called by Hibernate (i
think) and if the Entity is not a NHibernateProxy.
In fact, i have an exception in SessionImpl.cs in the method : public
object GetIdentifier(object obj)
(...)
if (obj is INHibernateProxy)
{
ILazyInitializer li = ((INHibernateProxy)
obj).HibernateLazyInitializer;
if (li.Session != this)
{
throw new TransientObjectException("The proxy was not associated
with this session");
}
return li.Identifier;
}
else
{
EntityEntry entry = persistenceContext.GetEntry(obj); //HERE IS THE
PROBLEM : not the good persistenceContext ??
if (entry == null) //entry is not find :(
{
throw new TransientObjectException("the instance was not
associated
with this session");
}
return entry.Id;
}
(...)
I don't know how resolve this problem :(
