Hi,

I have a bean that is taking to the page updateStudent.xhtml but is not populating the fields

The bewn is as below:

{code}

    public String loadStudent(int id){

        System.out.println("Printing something");

        try{

            Student theStudent = studentDbUtil.getStudent(id);

            ExternalContext externalContext =

                    FacesContext.getCurrentInstance().getExternalContext();

            Map<String, Object> requestMap = externalContext.getRequestMap();

            requestMap.put("student", theStudent);

        }

        catch(Exception e){

            e.printStackTrace();

        }

        return "updateStudent.xhtml";

    }

    public String updateStudent(Student student){

        studentDbUtil.updateStudent(student);

        System.out.println("test from update student controller");

        return "newjsf?faces-redirect=true";

    }

{code}

the page is:

{code}
