I have CFDocument generating a PDF. When the PDF opens, I can briefly see it as it should be. Then it disappears. Visibly gone anyway because I can find one of the images by clicking around, right click on it, copy it out and past it into an image editor. So the content is there but not visible. Any ideas what’s going on?
In our case this turned out to be a difference between servers. I guess there was a stealth update to CF7 that we picked up on one server and not the other. By stealth I mean that there were two hotfixes issued with the same ID that were different. To fix this our Sys Admin did a file by file comparison of all the CF .jar files and found what needed to be applied.
