    Description

      It's possible that this is expected behavior, and that what I'm trying to do is just not possible, but:

      When I have some fields in a document, then sign the document, then add a new field to the document and `saveIncremental` sign it, the prior signatures are invalidated.

       

      The message is "Document has been altered or corrupted since it was signed".

       

      The final signature on top of that is good, and the new field is there...but the old signatures are invalid. Is it possible to add a new field and not invalidate the old signatures? I've successfully edited existing fields, but can't get it a to be OK after adding a new field.

       

      I've attached a sample document.

       

      Thank you for your help!
