It will not be part of the view stack at all unless you want the user to be able to access it. Essentially until you add it it doesn't exist. When you do add the view with addChild() a button will be created automatically and the view will become accessible you shouldn't have to refresh anything. If the user has access to the view when they log on add it and it should appear if not it won't be there at all.
If thats not the functionality your looking for then a different approach is needed. Something similar to the following may be more appropriate for your needs. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" xmlns:views="views.*"> <mx:Script> <![CDATA[ [Bindable] private var HasAccess:Boolean = false; ]]> </mx:Script> <mx:ButtonBar id="myBar" dataProvider="{viewstack1}"/> <mx:ViewStack x="10" y="30" id="viewstack1" width="200" height="200"> <views:viewone/> <views:viewtwo id="viewtwo" show="HasAccess ? viewtwo.visible = true : viewtwo.visible = false"/> </mx:ViewStack> <mx:Button label="{this.HasAccess ? 'Access' : 'No Access'}" x="10" y="238" click="HasAccess ? HasAccess = false : HasAccess = true;"/> </mx:Application>
