using form data as subject and filename

Unfortunately there is no easy way to change the name of the file that is submitted. This data file is always named after the PDF. So the only way to change the name is to Save the file to a different name on the users local hard drive before submitting.

The email subject is much easier to change. You have two choices.

1) Use JavaScript to modify the underlying XML where the subject line is stored. You can see exacty where the subject is in the XML by selecting the email submit button on your form in LiveCycle Designer and then switching to XML view. Use the "MouseDown" event to make the change.

2) Use the Acrobat JavaScript "submitForm()" function to submit the email instead of the built-in LiveCycle submit button. Like this:

event.target.submitForm();
