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.

Answer 1

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);
