It works for me.

Mám stejný problém. Pravděpodobně nefunguje správně pokud je položka "Nastavení certifikátu" nastavena na "Zakázat změny". Pokud nastavím "Necertifikováno", tak připojování podpisů funguje správně.

To asi bude tim, ze certifikujici podpis muze byt jen jeden.

6.3.3 Support for two signature types

...

Certification: There can be only one certification signature and it must be the first one in a 

document. The field is always associated with DocMDP (See Controlling post-signing changes) and 

Legal content attestations. They may optionally be associated with FieldMDP permissions.

Aha... a jde to nějak detekovat? Aby to neplodilo rozbité pdf soubory?

[Josef Cacek]

Myslim, ze by to melo jit detekovat. Zkuste se podivat na API iTextu 2.1.7. Kdyz se potom podelite o opravu, budu rad. ;)

Hello,

I'm a new user. I really like the software. It works fine for the first signer. However, I noticed that  if a second person signs the document, the first signature dissappears. Is this normal?

Even the visible signature that was added by the first signer is removed.

Is there a way to have multiple signatures on a document (doc.pdf -> doc_signed1.pdf -> doc_signed2.pdf -> ...), where each signature is added on top of the preceeding signatures?

Thanks!

Marcel

There is a checkbox "Append signature to the existing ones" in the Advanced view. Try it, it should work for you.

Hello,

I'm a new user. I have a problem: I have to sign multiple locations at the same time in the same file. How can I do that?
Thanks!
