Display edit Employee's profile using jsf - jsf-2

Question

Using jsf I want to edit a employee profile, when user will click on any particular datatable row,then
I am able to get all that deatils of selected patient in an
arraylist. Now I want to set all the attritbutes in arraylist to
page1.xhtml backingbean , so When user will select a particular row,
he will navigate to page1.xhtml where he will get all these fields in
the form set already by arraylist attributes.
I am trying in this way.
> page1.xhtml
<h:outputLabel value="Name" />
<p:inputText id="name1" value="#{employeeBB.emp.name}" >
</p:inputText>
<h:outputLabel value="age" />
<p:inputText id="ag" value="#{employeeBB.emp.age}" >
</p:inputText>
<h:outputLabel value="code" />
<p:inputText id="code1" value="#{employeeBB.emp.code}" >
</p:inputText>
#ManagedBean(name = "employee")
#ViewScoped
public class emp {
private String name;
private String age;
private String code;
public String getName()
{ return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
}
#SessionScoped
#ManagedBean
public class EmployeeBB implements serializable{
private Employe emp;
public Employee getEmp() {
return emp;
}
public void setEmp(Employee emp) {
this.emp = emp;
}
}
#SessionScoped
#ManagedBean
public class AddEmployeeBB{
private ArrayList<Employee>empList;
private ArrayList<Employee>empList;
public ArrayList<Employee> getEmpList() {
if(empList==null){
empList=new ArrayList<Employee>();
}
return empList;
}
public void setEmpList(ArrayList<Employee> empList) {
this.empList = empList;
}
public void method() throws IOException{
String code='123';
EmployeeDAO obj=new EmployeeDAO(); // DAO class
empList=obj.getAllEmplInfo(code); // will get all needed information about employee of this code in this arrayist
for(int i=0;i<empList.size();i++){
String name=empList.get(i).getName();
String age=empList.get(i).getAge();
String code=empList.get(i).getCode();
Employee e=new Employee();
e.setName(name);
e.setAge(age);
e.setCode(code);
EmployeeBB obj1=new EmployeeBB();
obj1.setEmp(e); // now according to my logic object e will set to emp object of Employee, and
// that means all these values name ,agem and code will be set to my page1.xhtml and I will be able to see it.
}
}
But I am unable to get pag1.xhtml with filled values.
Show me the way.

The reason for it not being shown is that you are setting values in a object which you are creating
EmployeeBB obj1=new EmployeeBB();
obj1.setEmp(e);
JSF lifecycle doens't know about this object and everytime you are seeing blank.
In AddEmployeeBB add this
#ManagedProperty(value="employeeBB")
private EmployeeBB employeeBB = null; // create getter setter for this
then instead of this :
EmployeeBB obj1=new EmployeeBB();
obj1.setEmp(e);
Use this:
this.employeeBB.setEmp(e);
