wondering if anyone watching can make sense of this,
I'm try to work the memcache_client into my app, but every time it tries to read from memcache I get a Marshall error that the AR classes are not defined. But it's more vexing than that, as the error does not occur within the console. From a console everything works as expected, but when running in the app it fails.
Here is the backtrace...

Found this solution by Wes Gamble (thanks Wes) that seems to work...
"Memcached fails to retrieve object in a different controller - Rails - Ruby-Forum ;
But I have to say, it seems antithetical in a Rails app. I don't
necessarily think this is a memcache_client issue. I have another app
that uses memcache_client and I've not had any issue like this - very
curious.
