Here a little example, the combobox does a binding on the XML that is loaded by the model, and the Viewstack does a binding on the combobox's selectedItem.data :
file.mxml <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";> <mx:Model id="myOptions" source="test.xml" /> <mx:ComboBox id="mP" dataProvider="{ myOptions.item }"/> <mx:ViewStack id="myView" selectedIndex="{mP.selectedItem.data}" width="400" height="400"> <mx:HBox backgroundColor="#FF9900" width="100%" height="100%" hideEffect="Fade" showEffect="Fade"> <mx:Label text="View 1" /> </mx:HBox> <mx:HBox backgroundColor="#0099FF" width="100%" height="100%" hideEffect="Fade" showEffect="Fade"> <mx:Label text="View 2" /> </mx:HBox> </mx:ViewStack> </mx:Application> test.xml <doc> <item label="View 1" data="0"/> <item> <label>View 2</label> <data>1</data> </item> </doc> --- In [email protected], "Abdul Qabiz" <[EMAIL PROTECTED]> wrote: > It would still work, you have to write the logic to select the index of > ViewStack based on ComboBox selection.
