PDF acroforms無法在itext中正確復制

Question

因此，我有此PDF表單，並為其設置了字段：

   PdfReader reader = new PdfReader(src);
            PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest + i + ".pdf"));
            AcroFields form = stamper.getAcroFields();
            form.setField("name", "Bruno Lowagie");
            form.setField("adress", "ADDRESS");
            form.setField("dates", "January 1, 2010");
            form.setField("titles", "blah blah blah");
            stamper.close();
            reader.close();

但是，當我嘗試將所有文​​件復制到另一個文件時，字段僅顯示在字段的焦點上，請幫助

             Document document = new Document();
         PdfCopy pcf = new PdfCopy(document, new FileOutputStream(ALL_CUSTOMER_FILE));
         pcf.setMergeFields();
         document.open();


            int documentnumber = 0;
            for (String input : inputs) {
                PdfReader reader = new PdfReader(input);
                documentnumber++;
                renameFields(reader, documentnumber);
                pcf.addDocument(reader);
            }
            pcf.close();
           document.close();

對於遇到相同問題（當前使用itext 5.4.4）的用戶，我可以通過將AcroFrom的setAppearance設置為true並將setFormFlattatt設置為true來解決此問題：

        AcroFields form = stamper.getAcroFields();
    form.setGenerateAppearances(true);
    form.setField("name", "Bruno Lowagie" + i);
    form.setField("adress", "ADDRESS");
    form.setField("dates", "January 1, 2010");
    form.setField("titles", "blah blah blah");
    stamper.setFormFlattening(true);
