I was creating a form to be filled up by client and a submit button to send back the information to the server using Adobe LiveCycle Designer ES 9.0. When I tested the form using Adobe Acrobat Prof as a client, I can submit all information back to the server. And also when I tried to use Adober reader 8.0, it worked fine. However, when I tested using Adobe Reader 9 and 10, there was no postback from the client to server. Could anyone explain what is going on, and I really appreciate it.
