[nhusers] Issue with multiple Session handling

[Thenaruvi Vetriyarasu]

Hi All,

We have our web application built using NHibernate

When there multiple users using the web application, the NHibernate session
closed in one session affects the other, hence error messages like ISession
Closed is thrown. Similarly, when there are users updating data in the
screens that uses NHibernate, errors like 'This row was already modified or
deleted by another user ...' are thrown.

Any ideas to solve this issue will help us lot.

Thanks,
Thenaruvi

Thenaruvi,

In my experience this occurs when you hand out the same instance of
ISession to multiple requests or multiple threads. So when the instance is
closed or disposed on one it will closed or disposed on the others. I
generally try to setup my web applications using a DI tool of some sort, so
that my ISession's - through UnitOfWork & Repository - are handed out on a
per request basis. Tools like Ninject or Structuremap can help you
accomplish this.

My two cents....

I hope this helps.
