Thanks.
In the mean time I partially resolved using a PdfWriter instead of
PdfStamper.
I resume my purpose: what I'm trying to do is a PDF document obtained
filling the form fields and, at the end, adding a submit button which
submits the entire document.
The resulting document must be signed by the end user.

PdfReader filledTemplateReader = new PdfReader(new
ByteArrayInputStream(filledTemplateOutputStream.toByteArray()));
Document outputDocument = new Document(filledTemplateReader.getPageSize(1));
setupResponse(response, nomeFile);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputWriter = PdfWriter.getInstance(outputDocument, outputStream);
outputDocument.open();
PdfContentByte directContent = outputWriter.getDirectContent();
for (int i = 1; i < filledTemplateReader.getNumberOfPages(); i++) {
outputDocument.newPage();
PdfImportedPage page =
outputWriter.getImportedPage(filledTemplateReader, i);
directContent.addTemplate(page, 0, 0);
if (i == 1) {
addSubmitButton(outputWriter);
addJavascript(outputWriter);
}
}
outputDocument.close();
writeToResponse(response, outputStream);

I had a similar problem. Here's the high level code of
how I got around it... we're serving the pdfs out
through a bog standard servlet.
ServletOutputStream out = resp.getOutputStream();
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
PdfReader inputPDF = new PdfReader(docBytes);
PdfStamper stamp = new PdfStamper(inputPDF, baos);
PdfWriter writer = stamp.getWriter();
writer.setViewerPreferences(PdfWriter.HideMenubar |
PdfWriter.PageModeUseNone|PdfWriter.CenterWindow
|PdfWriter.NonFullScreenPageModeUseNone);
String nextIdList = calculateNextIdList(ids);
getButtonCreator().createEditButtons(inputPDF, writer,
stamp, nextIdList, String.valueOf(ids[0]));
getDocumentHelper().populatePreviouslySavedValues(ids[0],
stamp, true);
stamp.close();
resp.setContentLength(baos.size());
resp.setContentType("application/pdf");
out.write(baos.toByteArray());
resp.flushBuffer();
out.flush();
out.close();
Hope this helps.... my
getButtonCreator().createEditButtons does the actual
drawing of the buttons.
