I am trying to open a pdf with an XFA form in it. It gives the message:
Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document. You can upgrade to the latest version of Adobe Reader for Windows®, Mac, or Linux® by visiting http://www.adobe.com/go/reader_download. For more assistance with Adobe Reader visit http://www.adobe.com/go/acrreader.
This document contains some fields which arae not supported in viewer.
It has opened the file fine, this is the message designed to be shown if a viewer does not support XFA. I would be very surprised if Adobe planned XFA support for any new technology, this is not their announced future direction. Download and open in Reader.
