Hi -

I have a 3 classes (Component, Address, Payment. Address and Payment are also tables in the the database and I have created the mapping files for them.

My Component class contains two properties: AddressInformation (Address) and PaymentInformation (Payment) and does not have a related table in the database. My question is how do I set up the mapping file for Component so that I can call Session.Save(Component) and have the adress and payment information saved?

Thanks
Joe

Need more info to assist.

What's the relationship between the Address and Payment, then (?-to-?)? How are they related to each other in the db? If MyComponent carries no persistent data, what purpose does it serve?

Was to see how/if child classes were saved. After some digging I modified my Comonent and was able to get a little further along

Database Table:

Component
Id
AddressId
PaymentId

Class Definition:

Component
Id
AddressInformation
PaymentInformation


Mapping File:

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class name="Orders.Composite, Orders" table="tmpCompositeDebug" lazy="false">
<id name="Id" column="Id" unsaved-value="0">
<generator class="native"/>
</id>
<many-to-one name="AddressInformation" class="Orders.Address, Orders" column="AddressId" cascade="all" />
</class>
</hibernate-mapping>



UsageCode snippet from a test stub:






When I call the update method I would like for my Address table to be updated. Is there a way to do this, or do I need to call Save/Update for all child classes?

Thanks
Joe

I thought the cascade="all" would have taken care of that.

Needed to call flush.
