Please help on passing data..

Can someone please give me an idea on how can I pass my attributes to another view? Please please please.
In parsing my attributes,

  var x:XML = XML(event.result);     pntList = x..entry;     for (var i:int = 0; i < pntList.length(); i++){      var latlong:Array = pntList.point.split(" ");      var attributes:Object = new Object();      attributes.name = pntList.name; // attributes["name"]      attributes.region = pntList.region; // attributes["region"]      attributes.summary = pntList.summary; // attributes["summary"]

In accessing my attributes,

private function mClick(event:MouseEvent):void    {     var gra:Graphic = event.target as Graphic;     var vbox:VBox = new VBox();     vbox.height = 40;     vbox.width = 170;     vbox.label = gra.attributes.name.toString();          var button:Button = new Button();     button.height = 40;     button.width = 170;     button.label = gra.attributes.region.toString();     button.addEventListener(MouseEvent.CLICK, click);     vbox.addChild(button);         map.infoWindow.content = vbox;     map.infoWindow.closeButton.height = 15;     map.infoWindow.closeButton.width = 15;     map.infoWindow.show(gra.geometry as MapPoint);    }

This is my problem how can I pass my attributes to the view, Properties.. Please any idea? I tried some codes but didn't work... Please..

private function click(event:MouseEvent):void    {      navigator.pushView(Properties);    }

Understanding Flex Mobile View and ViewNavigator

If you want to pass some data from one view to another (for example an ArrayCollection or some other Data Model), then you can use the second argument of the navigator.pushView() method:
navigator.pushView(SecondScreen, myData);

@saibotehs, one way to do this if you have complex attributes is to set up a SharedObject. When the new view becomes active you can then grab the attributes from the SharedObject. The advantage of this pattern is it gives you a central location to manage all your application attributes. There's an example of this and other best practices built into this demo app: http://www.arcgis.com/home/item.html?id=f30c1e7747db417cae341fdeca2eb77e. All code is included.
