Defining a CustomType for KeyReference in CompositeId()

[m4cx]

Hey Guys,

I opened this topic within stackoverflow already, but until now there is no answer. Maybe you can have a look:

Thanks.

You're right, there is currently no support. To make matters worse, Fluent NHibernate does set the class attribute in the mapping, causing NHibernate to ignore entity-name. This causes mapping to any interface to fail.

My current workaround was to export the mapping to XML (using ExportTo), then using the XML mappings from the classes I couldn't properly map in code.

In short:

1. Fluent NHibernate should not set the class attribute unless specifically asked by the user. This is not something that could be done in a minor release as it can break working code.
2. Allow specifying the class of a KeyReference (key-many-to-one in XML).
