I need to add the total page count to a PDF/A-2 document created using iText in Java. The following code is being used:

public class HeaderFooterPageEvent extends PdfPageEventHelper 

 Font fontHEADER = null;

 /** The template with the total number of pages. */
 PdfTemplate total;

public HeaderFooterPageEvent() 
 try 
 fontHEADER = new Font(BaseFont.createFont("OpenSans-Regular.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED), 8, Font.BOLD);
 catch (DocumentException e) 
 e.printStackTrace();
 catch (IOException e) 
 e.printStackTrace();
 
 

 @Override
 public void onOpenDocument(PdfWriter writer, Document document) 
 total = writer.getDirectContent().createTemplate(30, 16);
 super.onOpenDocument(writer, document);
 

 @Override
 public void onCloseDocument(PdfWriter writer, Document document) 
 PdfContentByte cb = writer.getDirectContent();
 ColumnText.showTextAligned(total, Element.ALIGN_RIGHT,
 new Phrase(String.valueOf(writer.getPageNumber() - 1)),fontHEADER),
 document.right() - document.rightMargin()+5, 
 document.bottom() - 10, 0);
 super.onCloseDocument(writer, document);
 

And when creating the PDF the following code is called:

 Document document = new Document(PageSize.A4, 15, 15, 30, 20);

 PdfAWriter writer = PdfAWriter.getInstance(document, new FileOutputStream(dest), PdfAConformanceLevel.PDF_A_2A);
 writer.createXmpMetadata();
 writer.setTagged();

 // add header and footer
 HeaderFooterPageEvent event = new HeaderFooterPageEvent();
 writer.setPageEvent(event);

 document.open();
 document.addLanguage("en-us");
 File file = new File("sRGB_CS_profile.icm");
 ICC_Profile icc = ICC_Profile
 .getInstance(new FileInputStream(file));
 writer.setOutputIntents("Custom", "", "http://www.color.org", "sRGB IEC61966-2.1", icc);
 Paragraph p=new Paragraph("Page 1 content",fontEmbedded); //setting an embedded font
 p.setSpacingBefore(30f);
 document.add(p);
 document.newPage();
 document.add(new Paragraph("Content of next page goes here",fontEmbedded));


 document.close();

Now when we add content on 2 pages and use document.newPage() to add the new page, runtime exception is generated The page 3 was requested but the document has only 2 pages. What is a solution to this problem?
