I use this constr.
to display a popUp with PopUpManager.createPopUp etc.
But, because NumericStepper(NS) is imlemented with MXML, it does not exist in TitleWindow's(TW) display list when TW is ADDED_TO_STAGE.
so, when i try to setFocus on NS in different ways (can be more cpecific if you need) when it's added to stage, when TW is added or added_to_stage, etc.
it reveals to flash player crush or the error that ""NS isn't exist on stage, so can not setFocus on it"".
I need to setFocus() on NS when it appears, how can i do it with such this MXML implementation?
<s:NumericStepper id="stepper" creationComplete="stepper.setFocus()"/
