Thks, you are doing a great job.
I have one last problem that I've been working on. You probably know the
solution and it would save me a lot of time.
I Have a client - server application, I'm trying to sign the form on the
server so I'm calculating the Hash on the server transferring it to the client
to calculate the signature and pass it back to the server. How can I apply the
signature bytes? Do I use the PreClose?

The problem is that the signature field has a SigFieldLock dictionary under
the Lock key. I this case you should remove this key and make all the fields
read-only.

Your solution will break the field name rules by creating a field with a
'.'
in the name without using an hierarchy.
The code as exists still works for me. I just did some tests both in
Java
and C# and both worked. I would like to see that third party PDF, if
possible, otherwise I have to assume that your PDF is broken somewhere.
By
the way, working in Acrobat doesn't mean it's not broken.

For testing purposes I replace the line with
if ((fieldExists && name.IndexOf('.') >= 0) && (name != "sig.1"))
I was waiting to see your comments before doing any permanent changes.
If I test it with "if (fieldExists) {" I have the same problem. The
issue only happens when there is a "." In the name of the field.
