Nhibernate: <map> and <many-to-any>

Question

What I do wrong?

<map name="Aspects" table="AspectToEntity">
  <key column="EntityID" />
  <map-key column="AspectName" type="string" />
  <many-to-any id-type="long" meta-type="string">
    <column name="AspectName" />
    <column name="AspectID" />
  </many-to-any>
</map>

Exception:

Repeated column in mapping for collection: Entity.Aspects column: AspectName

Answer 1

You are using the same column name (AspectName) twice. Btw, what classes do you want to map? I think, the mapping file is not fully correct.
