As far as I can see, none of the available sites have a working product template allowing the eshop customer to select a product with multiple variants.
I have found 3 different approaches in the current eshop demo.
Only one of them (the old one, creating a picklist per variant group) seems to work - but it doesn't. If the customer selects variants in reverse order, then the previous selections are overwritten by default values.
So, could someone please take a look in mr. Dammarks secret drawers and check if there might be a working script or two? Preferably one rendering separate picklists, and one rendering a combined picklist.
It would be a great help if the proper folders of new sites contain templates for all available functionality. Supposedly the templates must exist somewhere among developers, so why not issue them along with the corresponding software functionality which they support?
