Bindable variable not updating with viewstack / swiz

Question

I'm using the Swiz framework and I'm trying to update my viewstack's selectedIndex with a bindable property. It gets to my event handler which updates the bindable variable but the Main app file's viewstack never realizes it. What could be the issue?

thx

MAIN APP FILE

<mx:Script>
    <![CDATA[
        import reg.model.ApplicationViewModel;
        import beyaz.reg.swiz.SwizBeans;
        import org.swizframework.Swiz;

        [Autowire(bean="applicationViewModel")]
        [Bindable]
        public var applicationViewModel:ApplicationViewModel;

        private function preInitialize():void {
            Swiz.loadBeans( [ SwizBeans ] );
        }

    ]]>
</mx:Script>


       <mx:ViewStack id="theViewstack" **selectedIndex="    {applicationViewModel.mainViewIndex}"** width="100%" height="100%">
    <prescreen:Prescreen id="prescreenView"/>
    <login:Login id="loginView"/>
    <profile:Profile id="profileView"/>

</mx:ViewStack>

=================================

ApplicationViewModel

package com.reg.model { public class ApplicationViewModel { public static const PRESCREEN_VIEW:int = 0; public static const LOGIN_VIEW:int = 1; public static const PRSNL_INFO_VIEW:int = 2;

    [Bindable] 
    public  var message:String = "";

    [Bindable]
    public  var mainViewIndex:int = PRESCREEN_VIEW;
}

}

===========================

Controller

package com.reg.controller {

import com.reg.model.ApplicationViewModel;

import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.events.DynamicEvent;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.core.Application;

import org.swizframework.Swiz;
import org.swizframework.controller.AbstractController;

public class PrescreenController// extends AbstractController
{
    public static const START_REGISTRATION:String = "startReg";

    [Autowire(bean="applicationViewModel")]
    [Bindable]
    public var applicationViewModel:ApplicationViewModel;


    [Mediate(event="startReg")]
    public function startReg():void 
           {

              //CODE GETS TO HERE!
              applicationViewModel.mainViewIndex = ApplicationViewModel.PRSNL_INFO_VIEW;

    }


}

I got bit by this problem just last week.

Put your [Bindable] tag before the other tags. For some reason the Flex compiler doesn't fold in the appropriate PropertyChangeEvent dispatching unless you put the [Bindable] tag first.
