Hi,

I realized (in development environment with caching activated) that  
cleaning the action cache for the show action is not working  
properly.  
The caching itself works fine - but once I try to clean the cache via  
the corresponding sweeper, the show action fragment does not get  
swept.

Here is the relevant sweeper method:  
def clear\_clientcontact\_cache(clientcontact)  
expire\_action(:controller =\> ‘clientcontacts’, :action =\>  
‘show’, :id =\> clientcontact.id)  
end

Here is the relevant logfile output:  
[Cached fragment hit: views/localhost:3000/clientcontacts/show/1]  
#this is the cached fragment  
Expired fragment: views/localhost:3000/clientcontacts/1 (0.0ms)

The problem seems to be that the expired fragment does not coincidence  
with the fragment the show action looks for: “views/localhost:3000/  
clientcontacts/show/1” (–\> “show” appears in the path) meanwhile the  
expired fragment has no “show” in the path.

Anyone knows why that happens and how I can resolve it?

Thanks for your help!
