PdfCopy doesn't handle fields, use PdfCopyFields.

Subject: [iText-questions] Problem duplicating PDF page. Using PdfCopy
andgetImportedPage
Hello to all.
I am having problems to implement in Java, the PDF Generation we run on PC’s
with a Delphi app.
I find iText very handy, but I ran into a problem, that after 3 days, is
driving me crazy.
We have PDF “templates” that are stored on the server. These are retrieved
by the PC and then using, Gnostice VCL Delhpi Component forms are inserted
with values, after duplicating the template page if necessary. Also, we
rename some fields on the original form.
I tried to emulate this logic with itext, but I ran into some problems.
Using the next code:
String plantilla = “/tmp2/ PDFSO15732R.pdf”;
Document document = new Document(); PdfCopy copy = new
PdfCopy(document, new FileOutputStream(
"/tmp2/salida.pdf")); document.open(); reader = new
PdfReader(plantilla); baos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader, baos);
stamper.setFormFlattening(false); AcroFields form =
stamper.getAcroFields(); form.renameField("Pagina","cambiado
"+i); form.setField("Cliente", "David");
stamper.close(); baos.flush(); reader = new
PdfReader(baos.toByteArray()); PdfImportedPage pagina_a_copiar =
copy.getImportedPage(reader, 1); copy.addPage(pagina_a_copiar);
copy.addPage(pagina_a_copiar);
copy.addPage(pagina_a_copiar);
The generated file salida.pdf looks fine.
Whenever I try to do a loop for this, like:
ByteArrayOutputStream baos; PdfReader reader;
PdfStamper stamper; Document document = new Document();
PdfCopy copy = new PdfCopy(document, new
FileOutputStream( "/tmp2/salida.pdf"));
document.open(); for (int i = 0; i < 3; i++) {
reader = new PdfReader(plantilla); baos = new
ByteArrayOutputStream(); stamper = new PdfStamper(reader,
baos); stamper.setFormFlattening(false);
AcroFields form = stamper.getAcroFields();
form.renameField("Pagina","cambiado "+i);
form.setField("Cliente", "David"); stamper.close();
copy.addPage(copy.getImportedPage(reader, 1));
copy.flush(); } document.close();
The first page is OK, but pages 2 and 3 are wrong. Also, the renamefield
works, but the setField sets the value (as I have seen from the step-by-step
debug) but the value is not there on the final output.I have downloaded the
iText source code, but I am unable to find where it is going wrong.
If I set the flatten to true, the result is even worst.
Maybe it is the template, but I have to find the way to overcome this, since
I cannot change the templates.
Also, if a open a PdfStamper on the generated pdf file (salida.pdf) and try
to retreive the AcroFields, the list is empty. This would not be a problem
If I could do the set Value on the loop itself, and the to add the fial
page. This is also not working, with the same problem above.
I have attached the template and output.
Thanks in advance for any help that an be provided.
Best regards, David
