This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I am using a multiple-page workflow, and on one page I need to input both a file and some textfields. Since it is a multi-page flow, I need to use the saveToken, isTokenValid methods to ensure correct input. Unfortunately I always get an false in istokenValid after the multipart form is submitted. Is there no possible workaround?
