Link to product in the order view
is it possible to link the product name in the order view to the product itself? Or are they "detached" after checkout?
I have only managed to put a link pointing to the product edit page by adding a relationship (commerce line item: product) and adding or editing a field with rewrite results.
If you want the path to where
If you want the path to where the customer added it to the cart, you are looking for: (Line Item) Commerce Line item: Display path. If you look the default Drupal Commerce cart view, that is what is used.
Now, if you want the link to the product itself, I believe you would need to create a simple view that would accept a product id as an argument from the URL and then display the fields you want to display. I would think showing the product display (instead of simply the product) would make more sense to the customer.
I presume you have the node
I presume you have the node title of the product display node as the product name? You can create relationships to show this in the order view http://www.apsinfrastructure.co.uk/blog/drupal-commerce-cart-node-fields
