       Body:
This patch does not open a new session to fetch the proxy data, it simply uses the current session if there is already one open. If there is no open session an exception will be thrown just like happens now.

The workarounds you suggest are not acceptable for the same reason that it is infeasible to initialize all proxies before sending them to the view layer--they may be contained within an arbitrarily complex object model.

I'm happy to help find a workaround for the technical issue of lazy loaded collections (I don't think it is impossible).

Description:
For discussion, please see the following forum topic:
http://forum.hibernate.org/viewtopic.php?t=42

In summary, there are scenarios in which it one may want proxies to be resolved in a different session.

The attached patch adds a ThreadLocal to SessionFactoryImpl which keeps track of the last opened session. If a the session that created a proxy is closed when it comes time to initialize the proxy, the last opened session is used instead, unless it has been closed as well.
