The code for a SHOW event runs before things are drawn to the screen. Sound like something is causing an extra invalidation of the children so they aren't ready right away. Can you make a simple test case?

As an experiment, I made the child createComponentsFromDescriptors and called validateNow() at the viewstack level. I also replaced the event listener with a timer since I have no idea what event to watch. All my attempts to make the child render itself aren't working- even if the timer waits for several seconds to allow an empty view to render, it still won't show up until after sliding in. Even once I get this working, I still won't know what event to listen for to know when the child's children are created. There's the lovely childrenCreationComplete event, but that's only dispatched for creation types of none and queued. Here's my current code: override public function set selectedIndex(value:int):void { _lastIndex = selectedIndex; if(value != _newIndex && value != _lastIndex && value >= 0 && _lastIndex >= 0) { _newIndex = value; var targetChild:Container = getChildAt(value) as Container; if (targetChild.mx_internal::numChildrenCreated < 0) { targetChild.createComponentsFromDescriptors(true); validateNow(); _creationTimer = new Timer(3000,1); _creationTimer.addEventListener(TimerEvent.TIMER,child_creation,false,0,true); _creationTimer.start(); return; } else { slideTabs(_lastIndex,_newIndex); } } } private function child_creation(event:Event):void { slideTabs(_lastIndex,_newIndex); } --- In [email protected]<mailto:flexcoders%40yahoogroups.com>, Alex Harui <aha...@...> wrote: > > I still believe that all children of a viewstack are created no matter the > creationpolicy.
