I have PDF with dynamic XFA - http://www.finanse.mf.gov.pl/documents/766655/1481810/VAT-7(17)_v1-0E_2017.pdf
I want to fill this PDF with XML (this is working) and set readonly field - which XML not contains - labeled as ‘2. Nr dokumentu’
I tried that:
document.Form.XFA[“Deklaracja.Strona1.Naglowek.RefID”] = “test”;
but its not working, how i can do this?
i think i must use field template (i can read it) and transform it to a field, but how?
PDF is signed and im using incremental save.
