Hi all, I created a form by using LiveCycle Designer ES4. The form has a submit button, and submit the XDP(include PDF) to the server by url. After apply the permission password to the form. Then will fail to submit the form and pop-up a msg say "The pdf document could not be saved and embedded in the XDP. This secure operation is not permitted.", how can i solve that?(here's my permission setting)ps. I have already apply Reader Extensions, and using Acrobat Pro DC/Reader DCThanks All.
