[flexcoders] checkbox - create a bindable "value"

[bmilesp]

Hello! I want a checkbox to return 0 or 1 instead of true or false 
respectively. Here's my component:

<?xml version="1.0" encoding="utf-8"?>
<mx:CheckBox xmlns:mx="http://www.adobe.com/2006/mxml";>
        <mx:Script>
                <![CDATA[
                        private var _value:Number;
                        
                        [Bindable]
                        public function get value():Number{
                                if(selected==true){
                                        _value=1;
                                        return _value;
                                }else{
                                        _value=0;
                                        return _value;
                                }
                        
                        }
                        
                        public function set value(val:Number):void{
                                if (val==1){
                                        _value=1;
                                        selected=true;
                                }else{
                                        _value=0;
                                        selected=false;
                                }
                        }
                        
                ]]>
        </mx:Script>
</mx:CheckBox>


When i try to bind a data model to the "value" property, it doesn't 
update the model when the value changes. However, when I do: 
click="Alert.show(value)", it  returns 0 or 1 as expected. So it 
seems that the internals are changing the value correctly, but the 
bind isn't working? Thanks for all your help! -bmiles
