Unable to bind to properties of actionscript object

Question

Hello Forum Folks,
I built a bread crumb object that extends UIComponent:
package com.XXX.bidboard
import mx.core.UIComponent;
public class BreadCrumb extends UIComponent
[Bindable]
private var _pageTitle:String;
[Bindable]
private var _component:String;
[Bindable]
private var _order:Number;
[Bindable]
private var _pageVisited:Boolean;
[Bindable]
private var _notLast:Boolean;
public function BreadCrumb()
super();
public function get pageTitle():String {
return _pageTitle
public function set pageTitle(value:String):void {
_pageTitle = value;
public function get component():String {
return _component
public function set component(value:String):void {
_component = value;
public function get order():Number {
return _order
public function set order(value:Number):void {
_order = value;
public function get pageVisited():Boolean {
return _pageVisited
public function set pageVisited(value:Boolean):void {
_pageVisited = value;
public function get notLast():Boolean {
return _notLast
public function set notLast(value:Boolean):void {
_notLast = value;
Then in an application object I try to create a BreadCrumb
object:
<bidboard:BreadCrumb
id="onePersonal"
pageTitle="Start"
component="personal_companies_wizard_start"
order="0"
pageVisited="true"
notLast="true" />
however, I get strange warnings:
warning: unable to bind to property 'notLast' on class
'com.XXX.bidboard::BreadCrumb'
warning: unable to bind to property 'pageTitle' on class
'com.XXX.bidboard::BreadCrumb'
warning: unable to bind to property 'pageVisited' on class
'com.XXX.bidboard::BreadCrumb'
Why? Everything seems to look correct. What is really strange
is that it only gives the warnings on notLast, pageTitle, and
pageVisited but not order or component. The only difference I can
tell betweeen the two groups are the fact that one group has
capital letters and other doesn't - However I can imagine this is
the cause of the problem. (I tried everything in lowercase and the
warning still appeared).
Any ideas? I'm willing to try anything to solve this mystery.
Did I miss something?
Thanks in advance!

Allow me to answer my own question. I found on Daniel's blog
http://life.neophi.com/danielr/2006/08/binding_error.html)
the answer to the unconverted Bindable metadata warning. Appearntly
if I switch the order of the setters and getters, such that the
setter show up first, the warning disappears. Not sure why the
flash engine needs it that way, but it does. All works now!
Thanks,
