undefined method `variant_options' in admin/orders/######/edit

Hi

In the admin, when I'm checking a particular order that has assembly products I'm getting:

undefined method variant_options' for #ActionView::Base:0x000000000302c8`

This line is in: /app/views/spree/admin/orders/_assemblies.html.erb:25. I can't find where is that method defined. What am I missing?

Thanks

Ok, I see the problem. The method was removed:
