Tilman Hausherr commented on PDFBOX-4433:
-----------------------------------------
It seems not to be supported (there is no class for it, nor is it mentioned in
the examples) but you can still add it by using the COS classes and methods, as
mkl did in his answer.

> 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
