I am using Livecycle Designed to create a form with 2 signature fields. In this form I there will be user input after signing the document.
How can allow changes afer the form is signed ? This way the signature panel will have the green check mark and not the yellow triangle(which implies dynamic changes).
In the Designer signature field object, you can create a collection of fields that you want to include and lock in the signature. In this way you can control what each signature will do.
No ....that is the nature of signatures. A signature will sign (include) everything in the PDF. So when you change the data it will invalidate the current signature. By signing it a second time you are including the previous signature and all additional data in the current signature.
