Mapping IDictionary with MappingByCode

Question

How can I map IDictionary<Entity, Component>? I've done this way:

Map<GeneralResourceType, Quantity>(x => x.BookedResources,
c =>
    {
        c.Key(ck => ck.Column("ProposedAction"));
        c.Table("BookedResources");
    },
k => k.ManyToMany(key => key.Column("ResourceTypeId")),
r => r.Component(qc => QuantityMapping.Mapping()));

(where GeneralResourceType is a mapped Entity and Quantity is a ValueObject). But during the call of BuildSession() exception is thrown:

NHibernate.MappingException : An association from the table BookedResources refers to an unmapped class: {MyNamespace}.Quantity. Seams like it tries to find ClassMapping for Quantity, while value part mapped as Component.

what if you leave out `r => r.Component(qc => QuantityMapping.Mapping())`? — Firo, Feb 14 '12 at 12:42
The same exception is thrown. Thanks for try though, cause i have no more ideas how I can fix this... — Alex Telegin, Feb 15 '12 at 06:52

First variant:
1. Map component in separate class inherited from ComponentMapping generic class.
2. Map dictionary property as follows:
```
Map(x => x.BookedResources, c =>
{
    //any options access, cascade etc
});
```

Second variant (inline):

Map(x => x.BookedResources, x =>
    {
        //any options access, cascade etc
    },
    x => x.Element(),
    x => x.Component(c =>
    {
        c.Class<Quantity>();
        c.Property(p => p.Amount);
        c.Property(p => p.Unit);
        // any other properties
    }
));
