I have a reference to a class that has a composite-id of two columns. I want to make the relationship with one column and one formula.

In hbm I would map it like this:

<many-to-one name="Tapa" update="false" insert="false">
  <column name="D_Tapa" />

And it works. But when I try to do it in fluent like this:

References(x => x.Tapa)

It doesn't recognize the formula and gives the following error:

NHibernate.FKUnmatchingColumnsException: Foreign key (FKEF1FC30E53D4A11E:mySecondTable [D_Tapa])) must have same number of columns as the referenced primary key (dbo.myTable [IdArt, IdColor])
   en NHibernate.Mapping.ForeignKey.AlignColumns(Table referencedTable)
   en NHibernate.Cfg.Configuration.SecondPassCompileForeignKeys(Table table, ISet`1 done)
