Maxime Fauberteau updated FLEX-34135:
-------------------------------------

    Attachment: MyButtonSkin.as

Custom Button Skin, which can manage null up/downBorderSkin.

No error was thrown if null was assigned to up/downBorderSkin properties.

> It seems that it could be impossible to assign a "null" skin to properties upBorderSkin and downBorderSkin.
> If you try to do that, an error was thrown in this function :
> override protected function commitCurrentState():void
> {   
>         super.commitCurrentState();
>         
>         borderClass = getBorderClassForCurrentState();
>         
>         if (!(_border is borderClass))
>             changeFXGSkin = true;
>         
>         // update borderClass and background
>         invalidateDisplayList();
> }
> Can you add a "non-null" test to be safer ?
> Furthermore, it is the only place where the "non-null" test isn't done...
