I can't make it to work for the HasMany part:
In the mapping for A class:
Map(x =>
x.UniqueIdentifier).Column("avUniqueIdentifier").Unique().Not.Nullable();
HasMany(x => x.Children)
.KeyColumn("avUniqueIdentifier")
.Table("Childrens");
In the mapping for B class:
References(x => x.Parent).Not.Nullable()
.PropertyRef(x=>x.UniqueIdentifier)
.Column("avUniqueIdentifier");
But I get the error:
15:22:55,795 ERROR [ 7] SchemaExport [(null)]- Column 'As.aId' is
not the same data type as referencing column 'Bs.avUniqueIdentifier'
in foreign key 'FK6B5005B1E3E18454'.
Could not create constraint.
If I remove the column name setter from
References(x => x.Parent).Not.Nullable()
.PropertyRef(x=>x.UniqueIdentifier);
nhibernate create 2 columns in the B table
