I have a class "Invoice Line" that has two properties that are of type "User defined structure".

The first one is QuantitySold and it is a structure called Quantity with two fields (Ammount and Unit).

The other is Price one is a structure called MonetaryValue and it also has two fields (Ammount and Currency)

How can I map each of these properties (QuantitySold and Price) to four columns (Quantity, Unit, Price, Currency)?

Can you do something like this:

<property name="QuantitySold.Ammount" column="per_qty" type="Int32" access="property"/>

<property name="QuantitySold.Unit" column="per_unit" type="String" length="50" access="property"/>

Thanks in advanced!

if these properties are inthe same table as the Invoice Line, you could create a Component:



obviously the mapping needs more detail. you could also create a UserDefinedType, but this seems easier to me at first blush.
