Michael Klink commented on PDFBOX-4433:
---------------------------------------
[~tilman] - to me this sounds a bit like a request for support for _signature
field lock dictionaries_ because the OP mentions "fields which have their own
signatures".
A related stack overflow answer: [“Lock” dictionary in signature field is the
reason of broken signature after
signing|https://stackoverflow.com/a/49964903/1729265].

> 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
