Hi, I would like to lock some fields when signing an specific signature field.
For this task I designed a AcroForm in a PDF with Acrobat where in a Signature Field I specified that when signed it must locks some fields. Tried with PDFbox, signed OK the field but the related fields were not locked. So, I guess I must add info to the signature to lock those fields. Googled about this but didn´t find anything, neither on examples. Any info or example would be really helpful. Thanks, Jonathan.
