I create a PDF form at AEM Form Designer 6.2. At the end, I was trying to add a Email submit button into form, I added email address, Email subject and set the Submit as PDF file and also, Presence as Visible at its object setting. However, when I tested the form at preview PDF. and clicked the Email Submit Button. It ran a while but shown nothing. Then I tested at the form itself. it still shown nothing. It should show a email sending choice, the outlook email should be included. It should be a very easy process. What is wrong?
