Thanks for the pointer.
Could anybody give me a hint on how the CocoonJs.ProductPrice are indexed? I tried to CocoonJS.Fetch("product3,product2,product5,product1, product4"), and I have the following:
CocoonJs.ProductPrice(0) gives the price of product5
CocoonJs.ProductPrice(1) gives the price of product4
CocoonJs.ProductPrice(2) gives the price of product3
CocoonJs.ProductPrice(3) gives the price of product1
CocoonJs.ProductPrice(4) gives the price of product2
I have no idea how they are arranged. Is it just random? Or have anything to do with the order you create/edit a product?
