Hi

I am trying to map to classes together using a many to many link.

I have no problem joining the two classes together when using the <bag> tag. However when I map the two classes together using the <map> tag as I want to use and Idictionary and run into a mapping error 'Repeated column in mapping for collection'

Is it possible to set nHibernate up so that the many-to-many will create a IDictionary list in the same way it would for a one-to-many

My current mapping file

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="ClassLibrary1.ClassA, ClassLibrary1" table="ClassA">
<id name="Id" column="Id" unsaved-value="00000000-0000-0000-0000-000000000000" access="field.camelcase">
<generator class="NHibernate.Id.GuidGenerator" />
</id>
<property name="Description" column="Description" access="field.camelcase" type="String" />
<map name="ClassBs" table="ClassAClassB" cascade="none" lazy="true" access="field.camelcase">
<key column="ClassAId"/>
<index column="ClassBId" type="Guid"/>
<many-to-many class="ClassLibrary1.ClassB, ClassLibrary1" column="ClassBId" />
</map>
</class>
</hibernate-mapping>
