> Hi All,
> Actually I wanted to ask a question, I could not find the appropriate place to ask. If there is a more appropriate place, please forward me.
> My question is that I want to sign documents in a sequence but between signings, I want to change some fields which have their own signatures. It is supported by PDF and until now I always used PDFBox but I could not achieve it.
> Whenever I sign a document and change a field and sign again, previous signature becomes invalid.
> How can I solve this problem?
> Regards
