TreeTable : My successful sorting

Question

Hi,
I have a tree table with a personal tree model.
So, here my work.
I have a bean Person.java :
import java.util.ArrayList;
import java.util.List;
*public class Person {*
*public Person(String name, String firstname) {*
_name = name;*
_firstname = firstname;*
_kids = new ArrayList<Person>();*
*public String getName() {*
*return _name;*
*public String getFirstname() {*
*return _firstname;*
*public List getKids() {*
*return _kids;*
*private final String _name;*
*private final String _firstname;*
*private final List<Person> _kids;*
I have a backing bean arbo3Bkb.java :
import java.util.ArrayList;
import java.util.List;
import org.apache.myfaces.trinidad.model.ChildPropertyTreeModel;
import org.apache.myfaces.trinidad.model.TreeModel;
import view.treeModel.bean.Person;
*public class Arbo3Bkb {*
*private TreeModel _model = null;*
private List<Person> people;
*public Arbo3Bkb() {*
super();
Person john = new Person("Smith", "John");
Person kim = new Person("Smith", "Kim");
Person tom = new Person("Smith", "Tom");
Person ira = new Person("Wickrememsinghe", "Ira");
Person mallika = new Person("Wickremesinghe", "Mallika");
john.getKids().add(kim);
john.getKids().add(tom);
ira.getKids().add(mallika);
*// create the list of root nodes:*
people = new ArrayList<Person>();
people.add(john);
people.add(ira);
*public void setModel(TreeModel _model) {*
*this._model = _model;*
*public TreeModel getModel() {*
*if (_model == null) {*
_model = new ChildPropertyTreeModel(people, "kids");*
*return _model;*
And I have a jspx : arbo3.jspx
*<?xml version='1.0' encoding='UTF-8'?>*
*<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"*
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
*<jsp:directive.page contentType="text/html;charset=UTF-8"/>*
*<f:view>*
*<af:document id="d1">*
*<af:messages id="m1"/>*
*<af:form id="f1">*
*<af:panelCollection id="pc1">*
*<f:facet name="menus"/>*
*<f:facet name="toolbar"/>*
*<f:facet name="statusbar"/>*
*<af:treeTable value="#{backingBeanScope.backing_arbo3.model}"*
var="node" id="tt1" rowSelection="single"
contentDelivery="immediate">
*<f:facet name="nodeStamp">*
*<af:column sortable="true" sortProperty="firstName"*
headerText="FirstName" id="c2" width="300">
*<af:outputText value="#{node.firstName}" id="ot1"/>*
*</af:column>*
*</f:facet>*
*<af:column sortable="true" headerText="Name" id="c1" width="300"*
sortProperty="name">
*<af:outputText value="#{node.name}" id="ot2"/>*
*</af:column>*
*</af:treeTable>*
*</af:panelCollection>*
*</af:form>*
*</af:document>*
*</f:view>*
*</jsp:root*
I get something like that :
- John
Kim
Tom
- Ira
Mallika
if I do an ascending sort, I get that :
- Ira
Mallika
- John
Kim
Tom
BUT it's not really what I want to get.
I would rather get this result :
- Ira
Mallika
- John
Tom
Kim
Do you see something wrong on my code?
Could you help me?
Regards,
Thomas

Thank you for answering my question!
But, I can't sort the children collection.
there is a BUG on METALINK : BUG:11929722 - CHANGE API TO BE ABLE TO USE THE SORT FEATURE IN TREE TABLES USING ADF BINDING. (There is no default sort support in ChildPropertyTreeModel and RowKeyPropertyTreeModel. This is intended for performance reasons.)

Thomas
