Component that references a component

[Bart Reyserhove]

Given the following class structure:

public class SalesItem

{

protected virtual IList<Price> prices {get; set;}

}

public class Price

{

public virtual Money Value {get; protected internal set}

}

So we have a SalesItem item that has many prices over time. Price is a value object that has a value of type Money which is also a value object.

In my fluent mapping I can do something like this:

HasMany<Price>(Reveal.Property<SalesItem>("Prices")).Component(price =>{price.References(x => x.Value);}

but this will not work since Money is also a value object. I guess I need something like this, but that is not supported.

HasMany<Price>(Reveal.Property<SalesItem>("Prices")).Component(price =>{price.Component(money => money.Map(x => x.Amount));}

Any ideas on how this can be solved.

Thanks,

Bart

I'd map your Money type as an IUserType, and then you should just be able to Map(x => x.Value).CustomType<MoneyUserType>().

The issue is that my Money class has two properties: Amount and Currency which means I cannot use a user type I guess. Am I correct that Fluent Nhibernate cannot map a component that references another component.

Currently, Fluent NHibernate supports a component that has an inner
component, as long as that component is NOT a member of a collection.
The reason for this is reasonably straightforward - a collection of
components is not mapped using <component>, but rather
<composite-element> and then further inner components are mapped using
<nested-composite-element>. Its the nested element that we haven't
implemented support for yet.
