Can't specify Key for JoinedSubclass with NHibernate.Mapping.Attributes

Description

I tried to use NHibernate.Mapping.Attributes.JoinedSubclass, but a joined-subclass requires a key child element, and when I specify the key as shown:

[NHibernate.Mapping.Attributes.JoinedSubclass(0,ExtendsType=typeof(Fund))]
[NHibernate.Mapping.Attributes.Key(1,Column="FUND_ROW_ID")]
public class PlanFund:Fund

I recieve this error:

error CS0592: Attribute 'NHibernate.Mapping.Attributes.Key' is not valid on this declaration type. It is valid on 'property, field' declarations only.

Environment

None

Key has nothing to do with RandomProperty, which makes this a kludge (and user interface kludges are issues). Maybe this isn't fixable or it's not worth fixing at this moment, but it really is an issue.

I don't see this as an "issue"; it is the way NHMA works...

I figured out a work around by moving the key attribute to the first property

[NHibernate.Mapping.Attributes.Key(0,Column="FUND_ROW_ID")]
[NHibernate.Property(1)]
public int RandomProperty

But that's kind of ugly and weird, but it produces the right xml so this could be a less priority bug.

Not an Issue
