FluentNHibernate-Defining a bag as an Element using Automapping

I have a class that has an IList of an enum type. Something like this :

public class Enitity
{

       public IList<Usages> Usages{get;set;} //Usages is an enum type

}

To define this relation I have implemented IHasManyConvention and IHasManyConventionAcceptance like this :

public class HasManyEnumTypeConvention:IHasManyConvention,IHasManyConventionAcceptance
{
public void Apply(IOneToManyCollectionInstance instance)
        {
            instance.Element.Type(instance.ChildType);
        }
}

public void Accept(IAcceptanceCriteria<IOneToManyCollectionInspector> criteria)
        {
            criteria.Expect(instance => instance.ChildType != null && instance.ChildType.IsEnum);
        }

When I try to build a Configuration object using this convention I get an exception as follow :

The element 'bag' in namespace 'urn:nhibernate-mapping-2.2' has invalid child element 'one-to-many' in namespace 'urn:nhibernate-mapping-2.2'

That I suspect that FluentNhibernate is adding both one-to-many and element elements to a bag. Obviously I am doing something wrong but I couldn't find any example that uses automapping to do the trick.

Please tell me how I can define a bag as an Element using FluentNhibernate Automapping ?

Okay I figured it out :) You should use an IAutomappingOverride implementation to define a bag as an element instead of one-to-many. Here's how I did it :

public class EntityOverride:IAutoMappingOverride<Entity>
    {
        public void Override(AutoMapping<RealEstateFile> mapping)
        {
            mapping.HasMany(x => x.Usage).Element("Usages").AsBag();
        }
    }
