NHibernate: Mapping a single column twice

Question

Is it possible to map one column twice using NHibernate?

<property name="CustomerID" index="IX_Customer" not-null="true" />
<many-to-one name="Customer" column="customerid" class="Customer" fetch="join" />

I need to have the raw ID in order to bind a WinForms control which only supports Binding using a value (instead of the Item itself).

 myControl.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", bs, "CustomerID", true));

Yes, just modify

<property name="CustomerID" index="IX_Customer" insert="false" update="false" not-null="true" />

Hm, is this working without getting an error like Jaguar mentioned? – falstaff Jan 26 '12 at 20:55
Didn't had any error since I used this solution, thanks! It's more a workaround for the moment, since I want to get rid of all those ID's.. – falstaff Feb 03 '12 at 13:11

you should find some other way to bind the id from the entity to your control
