Email Button format

Did you create the form in Acrobat or LiveCycle Designer? I ask because XML would be unusual for a form created in Acrobat, unless you mean XFDF. If you created the form in Acrobat and used a "Submit a form" type action, just go in and edit the button action (normally Mouse Up), and select PDF as the Export Format.

OK. Normally I'd send you over to the LiveCycle Designer forum, but it hasn't been working today. What you need to do is use a regular button, as opposed to an email submit button. Then open the Object palette for the button and select the Submit tab. There you'll see where you can enter a URL and select the "Submit As" format. Just choose PDF for the latter. For the URL, use a mailto type URL like:

mailto:someone@example.com

making sure to keep "mailto" in lower-case and don't include any spaces.

I forgot to add that if this needs to work with Reader, you'll need to Reader-enable the form. In Acrobat 9 you'd select "Advanced > Extend Features In Adobe Reader", but the wording is different for Acrobat 8.
