NHibernate: vekiller bir vatansız oturum hata iletisi tarafından alınamıyor

Question

Nesneyi almak, bir özelliği güncelleştirmek ve nesneyi veritabanına geri kaydetmek için nHibernate durum bilgisi olmayan bir oturum kullanıyorum.

hata mesajı almaya devam:

bu olmamasının sebebi

vekiller

başka yerde çalışan benzer bir kod var, bu yüzden çözemiyorum bir vatansız oturumda tarafından getirilemeyen Çalışma. Sorunun ne olabileceği hakkında bir fikri olan var mı?

ScreenLockVersion özelliğini güncelleştirmeye çalışıyorum.

Haritalama:

Vatansız oturumları tembel-yüklenmesini desteklemez. Screen varlıklarınızı erken yüklemeniz gerekir (aynı sorguda yalnızca proxy'leri yüklüyorsunuz).
