I fixed it! I just had to set Inverse=true. [HasMany(typeof(EcoShoppingCartItem), ColumnKey = "ShoppingCartId", Table = "EcoShoppingCartItems", Lazy = true, Inverse=true, Cascade = ManyRelationCascadeEnum.All)]
I'm not exactly what inverse=true means but got the idea from this link http://www.hibernate.org/359.html (bottom of page) and it works. Now, it doesn't actually delete the shoppingcartitem from the database, but it does disconnect it from the cart (sets shoppingcartid = null). Not ideal in this situation but I can see why we wouldn't want every thing removed from a collection to be deleted from the database so I'm happy with it. Now I've gotta figure out what inverse=true means.
