PERTAIN_TOProblem

only the last signture was displayed, the others remained invisible — I have a requirement to add multiple signatures to a document for a signer in one signing session.

PERTAIN_TOSolution

for (SignatureDefinition signatureDefinition : this.signatureDefinitions). Outcome: Now all the signatures created in the for loop.

PERTAIN_TOProblem

Invalid signature: Document is modified. — When trying to insert the certificate from the ESP response. Tension: signature become invalid when checked in adobe. Outcome: the hash of the signed document bytes is incorrect here.

PERTAIN_TOProblem

now signature is valid but user details is not there — if retrieving them from the signature is the only option you have. Tension: also does not support distributed system. Outcome: you have to know these user details in preparation phase before signing.

PERTAIN_TOSolution

you have to know these user details in preparation phase before signing — If you want the signature appearance to contain user details. Tension: If retrieving them from the signature is the only option you have. Outcome: you may have to create two signatures: The first one for dummy data to extract user details from the signature, the second one for the PDF prepared with those user details.

PERTAIN_TOSolution

you need to hash the prepared PDF (with signature dictionary containing the placeholder) — If you want any decent PDF signature validator to positively validate your signature. Tension: not something else. Outcome: validators expect that the signed byte ranges encompass exactly everything except the placeholder itself.

PERTAIN_TOProblem

A generated PDF intended to be PDF/UA-compliant consistently fails the PAC checker with the error "Test Object Not Tagged." The checker indicates required accessibility tagging is not being recognized.

PERTAIN_TOSolution

Update the PDF structure tagging implementation to correctly create and reference marked-content (PDMarkedContentReference with MCID), store structure elements in the ParentTree as a COSArray (even for a single element), set structure tree root parent tree keys correctly, and add the required PDF metadata/viewer/accessibility settings so PAC can resolve the tagged objects.
