How do I pass data between ViewNavigators in Flash Builder 4.5 Burrito

Question

I'm giving it a try and it happens that I'm having a hard time figuring out how to pass data between ViewNavigator in a TabbedMobileApplication.

<s:TabbedMobileApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark">
    <fx:Declarations>
    </fx:Declarations>

    <s:ViewNavigator id="nav1" label="Nav1" firstView="views.Nav1Home" width="100%" height="100%"/>
    <s:ViewNavigator id="nav2" label="Nav2" firstView="views.Nav2Home" width="100%" height="100%"/>

</s:TabbedMobileApplication>

How can I pass data between nav1 and nav2? I know how to do it in between navigation views.

Thanks, B.

Unless I'm missing something here, what you're going to want to do is and a script block in here and listen to your ViewNavigators for events. Then in th handler for the event, call a public functions on the targeted ViewNav.

<s:TabbedMobileApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" creationComplete="init()">
    <fx:Declarations>
    </fx:Declarations>

    <fx:script><![CDATA[
        private function init():void{
               nav1.addEvenListener(CustomEvent.DATA, onData);
        }

        private function onData(ev:CustomEvent):void{
               nav2.setData(ev.data);
        }
    ]]></fx:script>



    <s:ViewNavigator id="nav1" label="Nav1" firstView="views.Nav1Home" width="100%" height="100%"/>
    <s:ViewNavigator id="nav2" label="Nav2" firstView="views.Nav2Home" width="100%" height="100%"/>

</s:TabbedMobileApplication>
