The class 'com.beans.LoginBean' does not have the property 'message'

Question

I am trying to learn how the @NoneScoped as well as @ManagedProperty work but I am getting the error The class 'com.beans.LoginBean' does not have the property 'message' although I have message as prperty in the LoginBean class. What does that mean?

LoginBean

package com.beans;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.ViewScoped;
import javax.faces.context.FacesContext;

@ManagedBean
@ViewScoped
public class LoginBean {

    @ManagedProperty(value = "#{noneBean}")
    private NoneBean none;
    private String message;

    public void setNone(NoneBean none) {
        this.none = none;
    }

    public String setName() {
        none.setName(message);
        FacesContext.getCurrentInstance().addMessage(null,
                new FacesMessage("The name set for none scoped bean is: " + none.getName()));
        return "";
    }

}

NoneBean

package com.beans;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.NoneScoped;

@ManagedBean
@NoneScoped
public class NoneBean {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

I had to add the getter and setter method of the message property inside the LoginBean class.

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}
