Hi Christian, I came across this same problem too. However the next gotcha is that, as far as I can see, these same fields are then translated into Parameters when forwarded to your own servlet that you specify via the createUploadUrl. i.e. you need to send as hidden fields from your form, but then parse for parameters in your servlet that you arrive at after the blobstore created is made. The nasty bit, as you say, is that it works completely differently in DEV.
