Problem in CO extension to return to main page from Dialog Page

Question

Dear All,
I extended a CO and Over rode PFR.
My intention is to show a dialog page when "Submit" button is clicked. I am able to show a dialog page, but i am not able to return to the main page upon clicking "OK" in the dialog page.
Please find the code below in the PFR:
if (oapagecontext.getParameter("HrSubmit") != null)
          MessageToken[] tokens = { new MessageToken("MESSAGE", "Please add attachments")};
          OAException mainMessage = new OAException("AK","XX_CUST_MSG", tokens);
          OADialogPage dialogPage = new OADialogPage(OAException.ERROR, mainMessage, null, "", null);
          dialogPage.setRetainAMValue(true);
          dialogPage.setOkButtonItemName("OK");
          dialogPage.setOkButtonToPost(true);
          dialogPage.setPostToCallingPage(true);
          oapagecontext.redirectToDialogPage(dialogPage);     
if (oapagecontext.getParameter("OK") != null)
               super.processFormRequest(oapagecontext, oawebbean);
Though i am calling super.processFormRequest, the page is errroring out as soon as i press OK button in the dialog page.
Please let me know where i went wrong??
Thanks

Hi Centinul,
Thanks for the reply. I changed the code as you told, but it did not work.
Please find the below Code of PFR:
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
          super.processFormRequest(oapagecontext, oawebbean);
          OAApplicationModule rootam =oapagecontext.getRootApplicationModule();
          OAApplicationModule applicationModule = oapagecontext.getApplicationModule(oawebbean);
          String absType = (String)oapagecontext.getTransactionValue("AbsenceAttendanceTypeId");
          String absDur = (String)oapagecontext.getTransactionValue("DurationDays");
          String return_value,emp_name;
          int personId= oapagecontext.getEmployeeId();
          int absDays= Integer.parseInt(absDur);
          if (oapagecontext.getParameter("HrSubmit") != null)
               if (("65".equals((String)absType))&& (absDays>1))
                         try{
                              OADBTransaction txn = (OADBTransaction)applicationModule.getOADBTransaction();
                              OracleCallableStatement cs =(OracleCallableStatement)txn.createCallableStatement("Call xx_msft_loa_ppattach(?,?)", 10);
                              cs.setInt(1,personId);
                              cs.registerOutParameter(2,Types.CHAR);
                              cs.execute();
                              return_value = new String(cs.getString(2));
                              cs.close();
                              }//try
                         catch(Exception e)
                              System.out.println("error..... " + e.getMessage());
                              OAException confirmMessage = new OAException(e.getMessage(),OAException.ERROR);
                              throw OAException.wrapperException(confirmMessage);
                              }//catch
                    if ("NO".equals (return_value))
                         try{
                         OADBTransaction txn1 = (OADBTransaction)applicationModule.getOADBTransaction();
                         OracleCallableStatement cs1 =(OracleCallableStatement)txn1.createCallableStatement("Call xx_msft_loa_ppfullname(?,?)", 20);
                         cs1.setInt(1,personId);
                         cs1.registerOutParameter(2,Types.CHAR);
                         cs1.execute();
                         emp_name = new String(cs1.getString(2));
                              }//try
                         catch(Exception e)
                              System.out.println("error..... " + e.getMessage());
                              OAException confirmMessage = new OAException(e.getMessage(),OAException.ERROR);
                              throw OAException.wrapperException(confirmMessage);
                              }//catch
                         MessageToken[] nameTokens = {new MessageToken("EMP_NAME", emp_name)};
                         OAException mainMessageName = new OAException("AK","MSFT_LOA_PP_MSG", nameTokens);
                         OADialogPage dialogPageName = new OADialogPage(OAException.ERROR, mainMessageName, null, "", null);
                         dialogPageName.setOkButtonItemName("OK");
                         dialogPageName.setOkButtonToPost(true);
                         dialogPageName.setPostToCallingPage(true);
                         oapagecontext.redirectToDialogPage(dialogPageName);
                    }//NO if
               }//65 if
               }//HrSubmit if
else if (oapagecontext.getParameter("OK") != null)
                    oapagecontext.forwardImmediatelyToCurrentPage(null, true, null);
     }//PFR
Upon checking some conditions , i am redirecting to a dialog page after the submit button is pressed, in which i am showing a custom message and a OK button. My intention is after pressing the OK button, it should return back to the original page. i used 'forwardImmediatelyToCurrentPage' whihc is not working.
As soon as i press OK button, the page is erroring out, with out even showing the error stack. It only shows
'You have encountered an unexpected error. Please contact the System Administrator for assistance.'
Please let me know where i went wrong
Thanks
