myobj = Myobj.cached(:find\_by\_user\_id, :with=\>user\_id)

Debug gives:  
==\> Got Myobj:find\_by\_user\_id:1

BUT on expire\_cache:

==\>Deleted Myobj:1:find\_by\_user\_id

The key is totally screwed up.

I’m digging into the plugin code right now - but does anyone know if  
this is a bug or am I doing something wrong?

thanks.
