If your application has a VBox and Vbox has a child Button, to delete that
button, it SHOULDN'T BE this.removeChild(buttonId); Instead it should be
vboxId.removeChild(buttonId);
This can be the reason for that error in your case. Also, as Alex told, try to
see the numChildren and also see which are the children of your application.
eg. for(var i:int=0;i < numChildren;i++) {
trace(getChildAt(i));
}
Thanks,
