Guys, I am developing an application that shares a controller between multiple pages.

In first page there is a form that contain multiple buttons.

on first page button one is pressed it calls a method and assign value  to Controller attribute and display that contents in the second page in a input field

Seond page contain a button to render same content in PDF format .when button is pressed  it redirects to a another page and display content in pdf format that Works fine !!!!!

On the first page there is a another button to directly show the content in PDF format by redirecting direcly to third page but that doesnt work  PDF is render as empty document

point to note

• multiple pages share the same controller
• content rendered as pdf
• Same instance of the controller is used to access old value with out reinstantiation  (using PageReference.setredirect(false)  )

process works in two steps but same thing doesnt work in one step

step 1

public PageReference ViewMailInEditMode()

    
    {
        Map<String,String> formValues = new Map<String,String>();
        Id selectedEmp=employeeAssignment.Employee__c;
        String emailTemplate = this.emailTemplate;
        formValues.put('effectiveDate',String.valueOf(employeeAssignment.Effective_Date__c));
        formValues.put('id',selectedEmp);
        formValues.put('templateType',emailTemplate);
        if (emailTemplate.equals('Employee Extension'))
        {
            formValues.put('fromDate',String.valueOf(employeeAssignment.FromPeriod__c));
            formValues.put('toDate' ,String.valueOf(employeeAssignment.ToPeriod__c));
            formValues.put('currentDesignation',desgnationName);
            
        }
        EmailTemplates = new Email_Template__c();
        EmailTemplates.Body__c =EmailManager.CallMethod(formValues);
        PageReference pgRef = new PageReference('/apex/EmpAssignmentPrintview');
        pgRef.setRedirect(false);
        return pgRef;
    }

page 2

(printview)
  

<apex:page standardController="Employee_Assignment__c" extensions="EmployeeAssisgnmentExtension" id="page">
  
  <apex:pageBlock id="pageBlock1" >  
        <apex:form id="form1">
            <apex:inputField value="{!EmailTemplates.Body__c}"/>
            <apex:commandButton action="{!Save}" value="Print View"/>
        </apex:form>
    </apex:pageBlock> 
 </apex:page>

 step 2

•  public PageReference Save()
      {
  
          PageReference pgRef = new PageReference('/apex/EmpAssignmentPrintview2');
          pgRef.setRedirect(false);
          return pgRef;
      }

   

  page 3 (printview2)
  

• <apex:page standardController="Employee_Assignment__c" extensions="EmployeeAssisgnmentExtension" id="page" renderAs="pdf">
    <!-- Begin Default Content REMOVE THIS -->
    <apex:outputField value="{! EmailTemplates.Body__c}" />
    <!-- End Default Content REMOVE THIS -->
  </apex:page

   above code work fine

• code that sum up above two steps to one

   public PageReference pdfview()
      {
          Map<String,String> formValues = new Map<String,String>();
          Id selectedEmp=employeeAssignment.Employee__c;
          String emailTemplate = this.emailTemplate;
          formValues.put('effectiveDate',String.valueOf(employeeAssignment.Effective_Date__c));
          formValues.put('id',selectedEmp);
          formValues.put('templateType',emailTemplate);
          if (emailTemplate.equals('Employee Extension'))
          {
              formValues.put('fromDate',String.valueOf(employeeAssignment.FromPeriod__c));
              formValues.put('toDate' ,String.valueOf(employeeAssignment.ToPeriod__c));
              formValues.put('currentDesignation',desgnationName);
              
          }
          
         // System.debug('ssssssssssssssssssssssssss');
          EmailTemplates = new Email_Template__c();
          EmailTemplates.Body__c =EmailManager.CallMethod(formValues);
          System.debug('ssssssssssssssssssssssssss'+ EmailTemplates.Body__c );
         
         PageReference pgRef1 = new PageReference('/apex/EmpAssignmentPrintview2');
         
          pgRef1.setRedirect(false);
         
          return pgRef1;
       } 

   the above code doesnt work 

Any help would be great  !!!!!!!!!!!!!!!!!!!!!
