So I have this in my app/config/routing.yml:
acme_store_dev:
resource: "@AcmeStoreBundle/Resources/config/routing.yml"
host: acme.{tld}
requirements:
tld: dev|org

and something like this in the bundles routing.yml:
acme_store_homepage:
pattern: /hello/{name}
defaults: { _controller: AcmeStoreBundle:Default:index }
acme_store_product:
resource: "@AcmeStoreBundle/Resources/config/routing/product.yml"
prefix: /product

and the product.yml contains several auto generated routes like that:
product_show:
pattern: /{id}/show
defaults: { _controller: "AcmeStoreBundle:Product:show" }

The problem is within the first configuration. If I only use one host and no tld matching (and any other form of regex matching in hosts) itll lead to this kind of error:

An exception has been thrown during the rendering of a template ("Some mandatory parameters are missing ("tld") to generate a URL for route "category_new".") in AcmeStoreBundle:Category:index.html.twig at line 36.

I could now start rewriting all that the crud generator made for me or stop using that form of host matching, but Id really like to use those two features - any suggestions? is this a bug that can be fixed? from what I understand the /prefix is supposed to map route extensions dynamically, and independent of any prior routes, which is also quite nifty to have.
