Hi, I'm using the Welcome app (without any changes) and latest web2py trunk, and I'm having the same problem with pbreit code too.
This problem shows after a submit where the image has been changed, and it shows (immediately after the submit) that the image in the form (and even the image value: image.file.*) correspond to the *previous* image. If I do a refresh it shows the correct image. So it does save the latest image in the database but it shows the *previous* image in the form immediately after a submit with a different image. Have you tried with those situations and you don't present these problems?. Thanks again, Carlos
