I have 3 parent tables pointing to the same child table. I need to write the mapping. I've tried with "HasManyToMany" but i only achieved inserted two fields into the child table instead of the 3 fields.
HasManyToMany<Entity_A>(x => x.Entities_B).Table("CHILD_TABLE")
.ParentKeyColumn("A_ID")
.ChildKeyColumn("B_ID")
.Cascade.SaveUpdate();
Each of the 3 mappings have 2 of these blocks "HasManyToMany" everyone pointing to "CHILD_TABLE"
