Caches_action not generating full parameter route

Hi there,
I have a URL like this:
I’ve turned on caching in development mode, and my controller says:

caches_action :index, :list, :show

as well as

def show
@artwork = @artist.artworks.find(params[:id], :include => :tags)
@tags = @artwork.tags

but for some reason i only ever get the cache file:
with no id parameter

I’m running 1.2.3
anyone have any ideas?


ok, I answered that myself.
I had a route that was biting before the one I was expecting.
note to self - check routes, regularly.
