Hi everybody,
I'm trying to import a PDF File, populate it with form fields
and save the result. This works fine so far.

But if there are fields with the same name on different
pages of the document, iText seems to get difficulties with
the fields on the following pages.

If you open the resulting PDF with Acrobat (Reader) 5 and 
try to TAB through the fields, Acrobat crashes with a GPF.
Acrobat 6 is a little smarter, but doens't display the 
fields correctly. 

You can produce such a PDF with same named fields on different
pages with Acrobat 5 full version and it works fine.
In Acrobat (Reader) 6 they even implemented a new feature:
all fields with the same name are filled automatically with
the value of the changed field.

Is this a kind of bug in iText?
I'm using the latest version (iText-paulo-136) from
http://itextpdf.sourceforge.net

Any comments?

Best regards,
Peter

Here's some sample code. You need any PDF without AcroForm or Fields as an
input.


public class FieldsonPages
{

        public static void main(String[] args) 
        {
                String strInPDF = "D:/temp/without_fields.pdf";
                String strOutPDF = "D:/temp/with_fields.pdf";
                
                System.out.println("Testing fields on different pages");
                PdfReader reader;
                try 
                {
                        String strFeldName;
                        reader = new PdfReader(strInPDF);
                        FileOutputStream out = new FileOutputStream(strOutPDF);
        
                        Document document = new Document(reader.getPageSize(1));
                        PdfWriter aWriter = PdfWriter.getInstance(document, out);
                        
                        document.open();
                        int iPage;
                        for (iPage = 1; iPage <= reader.getNumberOfPages(); ++iPage) 
                        {
                                int iField = 0;
                                if (iPage != 1) {
                                        document.setPageSize(reader.getPageSize(1));
                                        document.newPage();
                                }
                                
                                PdfContentByte cb = aWriter.getDirectContent();
                                cb.addTemplate(aWriter.getImportedPage(reader, iPage), 
0, 0);
                                                        
                                strFeldName = "Field_" + iField;
                                Rectangle aRect = new Rectangle(100, 100, 350, 150);
                                TextField aTextField = new TextField(aWriter, aRect, 
strFeldName);
                                aTextField.setBorderWidth(1);
                                aTextField.setBorderColor(Color.black);
                                aWriter.addAnnotation(aTextField.getTextField());
                                iField++;

                                strFeldName = "Field_" + iField;
                                aRect = new Rectangle(100, 300, 350, 350);
                                aTextField = new TextField(aWriter, aRect, 
strFeldName);
                                aTextField.setBorderWidth(1);
                                aTextField.setBorderColor(Color.black);
                                aWriter.addAnnotation(aTextField.getTextField());
                                iField++;
                        }
                        
                        document.close();
                        
                } catch (IOException e) {
                        e.printStackTrace();
                } catch (DocumentException e) {
                        e.printStackTrace();
                }
                System.out.println("done");
        }
}
