I created a product field named "Features" which is set as Checkboxlist, and it returns a empty loop, when declared alone.
Calling just the loop, count returns 0
@GetLoop("Features.Options").Count
Calling the loop + the same field as string, count returns results and all the data-set
@GetLoop("Features.Options").Count
@GetString("Ecom:Product:Field.Features")
