[Plugin: WooCommerce] Variation dropdown

So, this fix no longer works with WooCommerce 2.1.

If I use the old file from 2.0.3 it won’t let me add items to the cart, they just don’t get added when I press the add to cart button.

If I change just that one line it breaks the page and only one variation selection menu shows up with just one blank option and nothing below that on the page shows up.

Would appreciate any insight. Thanks.
