Comment (by guest):

 How cynical of you to think that.

 The polymorphic_identity is a scalar. In case you would have multiple
 values to identify a class mapping by or even more complex needs, you
 could use a custom polymorphic map. That's what I interpreted the map as
 and since Michael [http://www.mail-
 archive.com/sql...@go.../msg01221.html once thought out
 loud] the use of the polymorphic map to be "OK", I considered this
 behaviour unintended.

 If the map is not intended to be used that way, however, I will look into
 the alternatives.


 Thanks,
 Thomas
