Fabio Maulo resolved NH-2070.
-----------------------------

       Resolution: Fixed
    Fix Version/s: 3.2.0Beta2

Fixed adding "or set cascade.." stuff.
The property involved is not available in that context.
There are other places where the same exception can show the property involved.

> In case when Merging object referencing transient instance NHibernate throws error:
> "NHibernate.TransientObjectException : object references an unsaved transient instance - save the transient instance before flushing. Type: Foo, Entity: Foo"
> This is not  very helpful in diagnosing the problem as it does not say how the object is referenced.
> A more helpful message would be:
> "NHibernate.TransientObjectException : Property Bar on object Foo is set to a transient object BarImpl- save the transient BarImpl before flushing (or set cascade action for the property to something that would make it autosave). Type: Foo, Entity: Foo"
