I am using jsf 2.2 and richfaces 4, My bean :

/**

package com.mkyong;

import java.util.ArrayList;

import java.util.List;

import javax.faces.bean.ManagedBean;

import javax.faces.bean.ViewScoped;

@ManagedBean

@ViewScoped

public class UserBean1 {

public List<String> autocomplete(String prefix) {

ArrayList<String> result = new ArrayList<String>();

result.add("England");

result.add("France");

result.add("Germany");

result.add("Italy");

result.add("Spain");

return result;

}

private String name;

private String state;

public String getState() {

return state;

}

public String getName() {

return name;

}
