I have the following classes and mappings:

public enum VariationType
{
    Base = 1,
    RiderMain = 2,
    RiderSpouse = 3,
    RiderChild = 4,
    Family = 5,
    FamilyBase = 6
}

public class PlanParameter
{
    private IDictionary<VariationType, PlanParameterDefaultValue> _defaultValues;

    public PlanParameter()
    {
        ParameterContext = new Parameter();
    }

    public virtual Parameter ParameterContext { get; set; }

    public virtual object DefaultValue { get; set; }

    public virtual string DefaultValueString
    {
        get
        {
            return DefaultValue == null ? null : DefaultValue.ToString();
        }
        set
        {
            DefaultValue = value == null ? null : Convert.ChangeType(value, ParameterContext.Type);
        }
    }

    public virtual IDictionary<VariationType, PlanParameterDefaultValue> DefaultValues
    {
        get
        {
            if (_defaultValues == null)
                _defaultValues = new Dictionary<VariationType,  PlanParameterDefaultValue>();

            return _defaultValues;
        }
    }
}

class PlanParameterMap : ClassMap<PlanParameter>
{
    public PlanParameterMap()
    {
        Id().GeneratedBy.Identity().Column("ID");

        References(x => x.ParameterContext,"ParameterID");

        Map(x => x.DefaultValueString);

        HasMany(x=> x.DefaultValues)
            .Access.CamelCaseField(Prefix.Underscore)
            .KeyColumn("PlanParameterID").Inverse()
            .AsMap("Variation")
            .Cascade.AllDeleteOrphan();
    }
}


public class PlanParameterDefaultValue
{
    public virtual PlanParameter PlanParameter { get; set; }

    public virtual object DefaultValue { get; set; }

    public virtual string DefaultValueString
    {
        get
        {
            return DefaultValue == null ? null : DefaultValue.ToString();
        }
        set
        {
            DefaultValue = value == null ? null : Convert.ChangeType(value, PlanParameter.ParameterContext.Type);
        }
    }
}


class PlanParameterDefaultValueMap : ClassMap<PlanParameterDefaultValue>
{
    public PlanParameterDefaultValueMap()
    {
        Id().GeneratedBy.Identity().Column("ID");

        Map(x => x.DefaultValueString);

        References(x => x.PlanParameter).Column("PlanParameterID");
    }
}

My problem is very specific to the mapping of the 

IDictionary<VariationType, PlanParameterDefaultValue> DefaultValues

The enum for some reason will not save, all that's saved in it's column is null my only solution so far was to add a VariationType Property to the Entity and map it with a lambda formula, but i really don't need the VariationType in the Entity

Am i doing something wrong?

Thanks very much

Inverse() 告诉 NHibernate “映射到”实体将负责保存密钥，并且集合所有者不应保留密钥。尝试删除该标志。
