removeChildAt() will only remove the specified object from the displaylist,
it won't destroy the object. Flex, by design keeps references to objects in
containers. You'll have to remove all references to a specfic object to
actually have it removed. We've run into some problems with this; this was
related to states, though, and this is also something which is by design.

Hi,
How come after calling removeChildAt(selectedIndex) within a viewstack
the child object still remains?
I've run basic tests to try get this working but no win.
I have a ViewStack based on this;
import mx.containers.ViewStack;
public class ExtVS extends ViewStack
{
// my new selectedIndex()
public function set updateSelectedIndex(index:Number):void
{
this.createComponentFromDescriptor(this.childDescriptors[index],false);
this.validateNow();
if (index > 0)
removeChildAt(selectedIndex);
}
}
And i've set it's creationPolicy="none".
I have 3 children. When i start the app in the debugger my children
look like this in the variables panel;
c1 = "childs.MyPanel"
c2 = null
c3 = null
By the time a proceed through each stack my debugger variables say;
c1 = "childs.MyPanel"
c2 = "childs.MyBox"
c3 = "childs.MyCanvas"
shouldn't it be
c1 = null
c2 = null
c3 = "childs.MyCanvas"
Also i am tracking totalMemory usage and i am receiving no benefits
compared to when i was not using removeChild()
Thanks,
Bjorn
