after a custom deployment on Teamcenter 10.1.6, out of the box xmlrenderingstylesheet disappeared. so i paste a custom xmlrenderingstylesheet code to the type of "dataset xmlrenderingstylesheet" for example and press "Apply" button then the code disappear after a while. i cannot write any xml codes to out of the box xmlrenderingstylesheet. my "Home Folder", "mailbox folder" or other out of the box items summary screen is now in a mess situation. can anyone any idea about this situation?
