Now I have had to make&nbsp;add a new view to the form template. After I had republish the changed template --- unfortunately all of the forms that have already been signed now show invalid digital signatures.</p> <p>Does anyone know a way to add a new view to an existing template without invalidating these signatures?</p> <p>In my opinion I was always thinking that the digital signatures signs the <strong>data</strong> of the form --- not the <strong>schema</strong> ;-((&nbsp;&nbsp;&nbsp; Isn´t that right?</p> <p>Thank you very much for any explanation.</p> <p>Karsten</p>
