Hi all,

In my OrdersController, I have two actions completed and incomplete  
that respond\_to HTML and CSV.

Im also action caching these actions

…  
caches\_action :completed, :incomplete  
…  
def completed  
@orders = Order.completed  
respond\_to do |format|  
format.html  
format.csv {render :layout =\> false}  
end  
end

def incomplete  
@orders = Order.incomplete  
respond\_to do |format|  
format.html  
format.csv {render :layout =\> false}  
end  
end

Now the cached fragments when I go to the CSV urls are

views/localhost:3001/orders/completed.csv  
views/localhost:3001/orders/incomplete.csv

My sweepers have the following cache expiration commands  
…  
expire\_action :controller =\> :orders, :action =\> :completed, :format  
=\> :csv  
expire\_action :controller =\> :orders, :action =\> :incomplete, :format  
=\> :csv  
…

But the log says

Expired fragment : views/localhost:3001/completed.csv  
Expired fragment : views/localhost:3001/incomplete.csv

notice that it missed “/orders” in there? The cache therefore never  
expires for the CSV format output. It works fine for HTML though. Any  
idea what im doing wrong?
