Good afternoon -

I'm working through the Lightning Components Developer Guide from DreamForce, and am getting an Internal Server Error when trying to Submit a new Expense. I've been through the code line-by-line, and have yet to find anything. Neither the Chrome or Firefox JS consoles show an error, and the System.debug() method around the "upsert expense; return expense;" code in the controller doesn't log anything. The error message says

An internal server error has occurred Error ID: 670155758-10800 (-1177185898)

Thanks!
