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}
