The form (PDF) must be rendered as a "Static" pdf (as opposed to Dynamic PDF). The current version of Digital Signatures ES can only sign static PDF document using the "Sign Signature Field" operation.
Dynamic PDF can have a "Certifying" signature created using LiveCycle Digital Signatures ES.
Thanks Steve for the reply
You can Sign a Dynamic Form if you follow these steps:
- Render Dynamic form XDP + XML with Forms
If you template does not have s Signature Field
- Add Invisible Field with Digital Signatures
- Sign the Signature Field you want with either Certify or Sign service.
