Thanks, setting creationPolicy="all"
in my sample app gets it to work but it’s still not working on the big
application I’m developing. It has a ViewStack nested inside another
ViewStack. I set creationPolicy="all" on both of them but the show
events are not firing the first time I view an item in the nested ViewStack. I
didn’t have this problem in Beta 1. Weird.

Beta 2 ViewStack Bug
I might be wrong but I think it's something to do
with the way things are inialized. trying setting the
"creationPolicy" to "all" like this
<mx:ViewStack
id="viewstack1" creationPolicy="all">
but don't set it on your childs. I've not tried
this... for some reason my browser keeps crashing everytime I try run Flex apps
in debug mode... dunno why. Just a warning though.... if you have alot of view
stacks... having "creationPolicy" set to "all" will slow
your application load time down ( only when it firsts gets initalized then
after it's all nice n fast :p )
hope this helps ;)

Hi,
I have a bug that I've noticed with the recent release of Flex 2 Beta 2.
The show event is not being dispatched when an item in a ViewStack
becomes visible for the first time. This problem was not present in Beta
1.
You
can use the code below to reproduce the problem. Run the application in
Debug Mode and you'll see that the trace statement does not get displayed until
the second time that you click the Forward button.
Is
there a workaround for this or do I need to wait for Beta 3? Thanks!

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml

<mx:ViewStack
id="viewstack1">
<mx:Canvas label="View 1" width="100%"
height="100%">
<mx:Button x="57" y="69" label="Forward"
click="{viewstack1.selectedIndex = 1}"/>
</mx:Canvas>
<mx:Canvas label="" width="100%" height="100%"
show="{trace('Show Called')}">
<mx:Button x="57" y="69" label="Back"
click="{viewstack1.selectedIndex = 0}"/>
</mx:Canvas>
</mx:ViewStack>
</mx:Application>
