url doesn't change with the attribute

[gbourelly]

Hello,

When I enter in a product page, the url stays with the default attribute and it doesn´t change when selecting another attribute.

So lets say my default attribute is size 5, so when I enter to the product I get ...hope.html#/5-color-grey/39-unisex_size-w5.

And if I select size 12, the url stays as ...hope.html#/5-color-grey/39-unisex_size-w5. It doesn't change.

So, if my product is out of stock the message can't appears.

I've tried to search a solution but I didn't find anything.

Thank you
