Hi!

I'm trying to do the following: type A has an IDictionary with elements of type B, indexed by B.Id. The collection has a corresponding table, A_to_B.

The mapping of type A looks like

Code:

<map name="Bs" table="A_to_B" ... >
   <key column="AID"/>
   <index column="BID" type="Int32" />
   <many-to-many column="BID" class="B, B"/>
</map>

This does not work, I get a "duplicate column" error for BID.
Is there any way to work around this?

Thanks,
Cris
