NH-2922 - Non-orphaned rows being deleted with cascade="all-delete-orphan"

[nhibernate-bot]

Phil Degenhardt created an issue — 26th October 2011, 1:38:33:

When a child is removed from a cascade="all-delete-orphan" bag and moved to a new parent (reparenting), NHibernate should throw an ObjectDeletedException with the message "deleted object would be re-saved by cascade (remove deleted object from associations)". This ensures that transactions will fail where users assume they can reparent such objects.

However, this exception is not thrown if the new parent object was loaded by the session before the current parent. In this case, the child object is deleted from the database and no warnings or exceptions are produced.

This bug has the potential to cause data loss and very difficult to find bugs.

Agree, but this isn't a blocker in my opinion, because it doesn't block anyone who is using NH correctly.

So what about the failing test case is using NH 'incorrectly'?
