I have been working on a form for the past few weeks. When I started this project, I was able to have a signature field on a PDF form and import it into Forms Central with no problems. The field would show up on my moble divices, I could sign it with the Pen tool, and then Submit the form. The Signature would show up when I downloaded the responces as a PDF and everything worked fine.
NOW... All of a sudden I get an error that I can not import the signature field and it will be ignored?!
Why the sudden Change? This is a deal breaker with forms central for us.
That is very odd. FormsCentral does not and has not supported Signatures.
This FAQ mentions the lack of support for Digital signatures in the Imported PDF: http://forums.adobe.com/docs/DOC-2533
I am not sure what you might have seen. The Import PDF feature has never supported Signatures and the form submit does not know about signatures and couldn't submit a signature to have it show up in the Response PDF you download from FormsCentral.
I am not sure what to tell you about what you had seen before, but a Signature workflow is not supported when collecting responses through FormsCentral.
