I'm trying to associate a list/array of Content Types to a Product, i.e, i have several content types and when creating a Product, on Sitefinity Ecommerce, i need to associate this Product with several content types.
So far i created a Dynamic Field Selector to select several conten types on the Product, this works fine until the moment i try to save it and a serialization error is thrown since i can't set the Type of this field as a Guid[], like on Content Types fields, so i selected as long text. But since it's trying to convert a Guid[] to string it throws a error.

Anyone as any ideia on how to do this or a hint so i can follow up?
