Jquery Mobile/DrupalGap/Cordova useCachedFile abnormality

[gs9999]

I am experiencing a malfunction ( my script doesn't execute properly), when I call the useCachedFile command. I can set the cache, but when it comes time to read it I am experiencing some kind of malfunction.

There is a type error 'uri.length' object type error that is executing in the console log.

I don't know... can someone start me off on some sort of direction to look?
I am alternatively going to try to implement my own caching system using the cordova file system, but thought I would check first with you folks.
