I think I messed something up pretty bad. I used to have an iframe upload working perfectly in my CTF popup. After saving, the message "You can add files ones you have saved for the first time" would disappear and I'd get the FileIFrameField immediately. Now I have to close the window and reopen it with the edit button to get it to show.
Any idea what I might have done? It looks as if the form is submitting via ajax so it never reloads. Maybe before it wasn't?
