[papachan]

Hello there,

Do you have noticed that in Flex4, ViewStack.selectedIndex is not refreshing with Bindable variables?

I have a same example working in flex3 but in flex4 not....

weird.

sorry, it finally worked into a brand new empty Project at flex4. My code on my old project seems not to be so correctly achieved.

   <fx:Script>
      <![CDATA[
         [Bindable]private var model:ModelLocator = new ModelLocator();
         
         protected function first_clickHandler(event:MouseEvent):void
         {
            model.viewIndex = 1;
         }
         
         
         protected function btn_clickHandler(event:MouseEvent):void
         {
            model.viewIndex = 0;

         }
         
      ]]>
   </fx:Script>
   <fx:Declarations>
      <!-- Place non-visual elements (e.g., services, value objects) here -->
   </fx:Declarations>
   <s:HGroup>
      <s:Button  click="first_clickHandler(event)"/>
      <s:Button click="btn_clickHandler(event)"   id="btn"  />
   </s:HGroup>
   <s:Panel id="dataPanel" width="840" height="100" y="100">
      <mx:ViewStack id="myViewStack" selectedIndex="{ model.viewIndex }"
                 width="100%" height="100%">
         <mx:Canvas id="PanelEditor">
            <s:Button id="btn1" label="Button #1" />
         </mx:Canvas>
         <mx:Canvas id="SiteEditor" show="btn2.label = new Date().toTimeString();">
            <s:Button id="btn2" label="Button #2" />
         </mx:Canvas>
      </mx:ViewStack>
   </s:Panel>

do you mean the code logic was wrong in the first project thats why it didnt work? also is this only a test project? i see you are setting the model in the main class instead of through some event dispatcher or command to sets the model.

[papachan]

The code above is only a simple exemple to validate a binding variable, working with a viewstack component in flex4.

My problem at my first project, was using a binding variable from a model class and triggered from an eventdispatcher. but the project use already many classes and wouldnt paste it here.
