and this my viewmodel (MstStudentVM.java)

package com.myapp.viewmodel.mst;

import java.util.ArrayList; import java.util.List;

import org.zkoss.bind.ValidationContext; import org.zkoss.bind.Validator; import org.zkoss.bind.annotation.Command; import org.zkoss.bind.annotation.Init; import org.zkoss.bind.annotation.NotifyChange; import org.zkoss.bind.validator.AbstractValidator; import org.zkoss.zul.ListModel; import org.zkoss.zul.ListModelList;

import com.myapp.bean.Student;

/* @author Pro Gamer Feb 27, 2013 11:13:41 AM */

public class MstStudentVM {

private Student current,search;

private ListModelList<Student> listModel;

@Init
public void init(){
    List<Student> list = new ArrayList<Student>();
    list.add(new Student("1", "Student 1"));

    listModel = new ListModelList<Student>();
    listModel.addAll(list);
}

public Student getSearch() {
    if (search == null) search = new Student();
    return search;
}

public void setSearch(Student search) {
    this.search = search;
}

public Student getCurrent() {
    if (current == null) current = new Student();
    return current;
}

public void setCurrent(Student current) {
    this.current = current;
}

    if (listModel == null){

    this.listModel = listModel;
}

@NotifyChange("listModel")
@Command("save")
public void save(){
    System.out.println("obj current "+current);
    listModel.add(current);

}

@NotifyChange({"listModel","search"}) 
@Command("search")
public void search(){
    // stack here, how to get object from UI -> textbox Id and textbox Nama
    if (search != null){
        System.out.println("search id "+search.getId());
        System.out.println("nama id "+search.getNama());

    }

}

@NotifyChange("current")
@Command("reset")
public void reset(){
    current = null;
}

public Validator getFormValidator(){
    return new AbstractValidator() {

        public void validate(ValidationContext ctx) {
            // TODO , masbro
            String id = (String) ctx.getProperties("id")[0].getValue();
            if (id == null || id.equalsIgnoreCase("")){
                addInvalidMessage(ctx, "fkey1", "id is empty bro");
            }
            String nama = (String) ctx.getProperties("nama")[0].getValue();
            if (nama == null || nama.equalsIgnoreCase("")){

            }
        }
    };
}

}

and this is Student.java (bean)

    this.id = id;

public String getNama() {
    return nama;

    this.nama = nama;
}

@Override

    final int prime = 31;
    int result = 1;
