Does the field you have on your page three happen to share a name with a field on any of the other pages? This may be an elementary question, but it's the first thing I thought of.
Below is a class I used to combine documents, you may find it helpful.
Cheers,
Brian
public class ConCat2DocsWithFields {
public static void main(String[] args) throws IOException,
DocumentException {
System.out.println("Printing PDF file ..");
Document document = new Document();
PdfCopyFields copy = new PdfCopyFields(new
FileOutputStream(
"c:\\dxl\\renderOut1.pdf"));
document.open();
PdfReader reader1 = new
PdfReader("c:\\dxl\\PersonDevice.pdf");
PdfReader reader2 = new
PdfReader("c:\\dxl\\PersonDevice1.pdf");
copy.addDocument(reader1);
copy.addDocument(reader2);
copy.close();
document.close();
System.out.println("Done!");
}
}

Subject: [iText-questions] problem appending PDF files
I have a problem appending a PDF file containing form fields to another
PDF without losing the form fields. I have files which illustrate this
issue.
I am using iTextSharp-5.3.0 (I tried upgrading to iTextSharp-5.4.0 but
other code in my application broke, so I had to continue to use this
version.)
I have two PDFs with form fields which I populate independently.
www.dropbox.com/s/x2lk6h6nz0ocurl/Page1%262.pdf
www.dropbox.com/s/za4r79ag55qat2a/Page3.pdf
I then use the following code to combine the files:
// Assemble PDFs into one large file
MemoryStream msFinal = new MemoryStream();
using (FileStream fs = File.Open(_pdfFile, FileMode.Open))
{
msFinal.SetLength(fs.Length);
fs.Read(msFinal.GetBuffer(), 0, (int)fs.Length);
fs.Close();
}
msFinal.Position = 0;
File.Delete(_pdfFile);
iPage = 3;
pdfReader = new iTextSharp.text.pdf.PdfReader(msFinal);
PdfStamper pdfFinal = new PdfStamper(pdfReader, new
FileStream(_pdfFile, FileMode.Create));
foreach (String _pdfout in _pdfs)
{
if (_pdfout != _pdfFile)
{
MemoryStream ms = new MemoryStream();
using (FileStream fs = File.Open(_pdfout, FileMode
.Open))
{
ms.SetLength(fs.Length);
fs.Read(ms.GetBuffer(), 0, (int)fs.Length);
fs.Close();
}
ms.Position = 0;
PdfReader pdfReader3 = new iTextSharp.text.pdf.
PdfReader(ms);
pdfFinal.InsertPage(iPage,
pdfReader.GetPageSize(1));
pdfFinal.ReplacePage(pdfReader3, 1, iPage);
pdfReader3.Close();
ms.Close();
iPage++;
}
}
try
{
pdfFinal.Close();
}
catch { }
pdfReader.Close();
The result is this file:
www.dropbox.com/s/b8hkkkav76zegwq/Page1%262%263.pdf
Basically, the form fields are correctly populated from the first file,
but when I use replacepage to copy the contents of the 3rd page, I do not
get the form fields at all on the page 3.
Not quite sure what I am doing wrong.
I have found if I create Page 3 with:
pdfFinal.FormFlattening = true;
pdfFinal.FreeTextFlattening = true;
pdfFinal.SetFullCompression();
Then the data will, in fact, show up. However, I really need to have the
form fields intact for further editing by the user.
Hopefully I?ve explained this well? Any help on this issue would be
appreciated, I really need to consolidate the files into one large PDF
without losing the contents of the 3rd page. If there is a different
approach to appending the files together, a pointer to an example would
likewise be appreciated.
