I recently implemented a reporting model in my app (a windows service) and so now have two session factories to manage within a unit of work. Originally, I was using this setting:

<property name="current_session_context_class">thread_static</property>

This was causing the wrong session to get injected into my entities since only one session factory is supported with this setting. So I changed it to this:

<property name="current_session_context_class">call</property>

Now things work as expected. You don’t want to use this on ASP.NET.
