Pdf Annotaion and Tab order error.

Hi All,



I have created a pdf file with list of states table in first page and when
you click the link it takes to the page, on the state page there is link
again to come back to the list of states page.



The attached document has pdf screen shots and error report.



My Code snippet to create the pdf is as follows :



1: to create pdf table with links :

*private* PdfPTable createStateLinksTable(List<OcseMatrixDO>
empServInfoList) *throws* DocumentException{





              PdfPTable pdfTable = *new* PdfPTable(3);

              pdfTable.getDefaultCell().setBorder(0);

              pdfTable.getDefaultCell().setPaddingTop(100f);



              *int*[] tableWidth = *new* *int*[3];

              tableWidth[0] = 200;

              tableWidth[1] =200;

              tableWidth[2] = 200;

              pdfTable.setWidths(tableWidth);

       //     pdfTable.setTotalWidth(500f);

              pdfTable.setTotalWidth(600f);



              Font link = FontFactory.*getFont*(FontFactory.*HELVETICA*,
12, Font.*UNDERLINE*, Color.*BLUE*);

              OcseMatrixDO ocseMatrixDO = *null*;

              PdfPTable stateTable1 = *new* PdfPTable(1);

              PdfPTable stateTable2 = *new* PdfPTable(1);

              PdfPTable stateTable3 = *new* PdfPTable(1);

              stateTable1.getDefaultCell().setBorder(0);

              stateTable2.getDefaultCell().setBorder(0);

              stateTable3.getDefaultCell().setBorder(0);



              PdfPCell addCell1;

              Chunk chunk1 = *null*;



              addCell1 = *new* PdfPCell(*new* Phrase(" "));

              addCell1.setBorder(0);



              pdfTable.addCell(addCell1);

              pdfTable.addCell(addCell1);

              pdfTable.addCell(addCell1);



              *int* geoListSize = empServInfoList.size();

              *for*(*int* g=0; g<geoListSize; g++ )

              {

                     ocseMatrixDO = empServInfoList.get(g);



                     chunk1 = *new* Chunk(ocseMatrixDO.getGeoName(),
link).setLocalGoto(" "+ocseMatrixDO.getGuid());

                     addCell1 = *new* PdfPCell(*new* Phrase(chunk1));

                     addCell1.setBorder(0);



                     *if*(g<(geoListSize/3))

                           stateTable1.addCell(addCell1);

                     *else* *if* (g<((geoListSize * 2)/3))

                           stateTable2.addCell(addCell1);

                     *else*

                           stateTable3.addCell(addCell1);

              }

              pdfTable.addCell(stateTable1);

              pdfTable.addCell(stateTable2);

              pdfTable.addCell(stateTable3);



              *return* pdfTable;

       }



2: to render the pdf table using content byte :

*private* *void* setStateLinksData(PdfWriter writer, List<OcseMatrixDO>
empServInfoList) *throws* MalformedURLException, DocumentException

       {

              PdfPTable pdfTable = createStateLinksTable(empServInfoList);



              PdfStructureTreeRoot root = writer.getStructureTreeRoot();

              PdfStructureElement linktable = *new*
PdfStructureElement(root, *new*    PdfName("Table"));

              linktable.put(PdfName.*LANG*, *new* PdfString("en-us"));

              *int* columnCount      = 3;

              *float* xPos = 145;

        *float* yPos =525f;



        *float* widths[] = pdfTable.getAbsoluteWidths();

        pdfTable.setHeaderRows(1);



              *for*(*int* i=0; i < pdfTable.size();  i++) {

                     PdfContentByte canvases[] = PdfPTable.
*beginWritingRows*(writer.getDirectContent());



               PdfStructureElement tr = *new*
PdfStructureElement(linktable, *new* PdfName("TR"));

               tr.put(PdfName.*LANG*, *new* PdfString("en-us"));

               *for*(*int* j = 0; j < columnCount; j++) {

                     PdfStructureElement td = *null*;

                     *if*(i==0)

                            td = *new* PdfStructureElement(tr, *new*
PdfName("TH"));

                     *else*

                            td = *new* PdfStructureElement(tr, *new*
PdfName("TD"));

                     td.put(PdfName.*LANG*, *new* PdfString("en-us"));



                   PdfContentByte cb = canvases[PdfPTable.*TEXTCANVAS*];

                   cb.beginMarkedContentSequence(td);

                   *if*((j+1) == columnCount) {

                     yPos = pdfTable.writeSelectedRows(j, j + 1, i, i+1,
xPos,yPos, canvases);

                          xPos = 145;

                   } *else* {

                      pdfTable.writeSelectedRows(j, j + 1, i, i+1, xPos ,
yPos,    canvases);

                        xPos += widths[j];

                   }

                   cb.endMarkedContentSequence();

               }

               PdfPTable.*endWritingRows*(canvases);

              }



       }



3: to create link of each state details page:



*private* *void* getStateLinksData(PdfWriter writer, *boolean*
isDestination) *throws* DocumentException

       {

              Font link = FontFactory.*getFont*(FontFactory.*HELVETICA*,
10, Font.*UNDERLINE*, Color.*BLUE*);

              PdfStructureElement div = *new*
PdfStructureElement(writer.getStructureTreeRoot(), *new* PdfName("Span"));

              div.put(PdfName.*LANG*, *new* PdfString("en-US"));



              PdfContentByte cb = writer.getDirectContent();



              *float* xPos = 680;

              *float* yPos = 480;



              *if*(isDestination){

                     xPos = 350;

                     yPos = 450;

              }



              cb.saveState();

              cb.beginMarkedContentSequence(div);

              cb.beginText();



              *if*(isDestination){

                     PdfDestination pdfDest = *new*
PdfDestination(PdfDestination.*XYZ*,-1,-1,0);

                     cb.setFontAndSize(link.getBaseFont(), 12);

                     cb.showTextAligned(PdfContentByte.*ALIGN_LEFT*, "List
of States", xPos, yPos, 0);

                     cb.localDestination("STA", pdfDest);

              }*else*{

                     cb.setFontAndSize(link.getBaseFont(), 10);

                     cb.setColorFill(Color.*BLUE*);

                     cb.showTextAligned(PdfContentByte.*ALIGN_LEFT*, "List
of States", xPos, yPos, 0);

                     cb.localGoto("STA", xPos, yPos, xPos+60, yPos+5);


              }



              cb.endText();

              cb.setColorFill(Color.*BLACK*);

              cb.endMarkedContentSequence();

              //cb.restoreState();

              cb.saveState();

       }
