Description

(Apollo:Application isn't the exact 'Feature' - but the closest related one listed)

Reproduction:

<?xml version="1.0" encoding="utf-8"?>
<mx:ApolloApplication xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
mouseDown="onMouseDown(event)"
backgroundColor="0x003030"
focusRect="false">
<mx:Script>
<![CDATA[
import mx.managers.CursorManager;

private var _mouseHidden:Boolean = false;

private function onMouseDown(event:MouseEvent):void
{
try {
_mouseHidden = !_mouseHidden;
if (_mouseHidden)

{ CursorManager.hideCursor(); }

else

{ CursorManager.showCursor(); }

}
catch(e:Error)

{ trace(e); trace(e.getStackTrace()) }

}
]]
>
</mx:Script>
</mx:ApolloApplication>

Actual Results: an exception is thrown on both hide- and showCursor calls. The mouse cursor is not being hidded / shown:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.managers::CursorManagerImpl/hideCursor()[C:\dev\flex_201_ja\sdk\frameworks\mx\managers\CursorManagerImpl.as:268]
at mx.managers::CursorManager$/hideCursor()[C:\dev\flex_201_ja\sdk\frameworks\mx\managers\CursorManager.as:178]
...

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.managers::CursorManagerImpl/showCursor()[C:\dev\flex_201_ja\sdk\frameworks\mx\managers\CursorManagerImpl.as:256]
at mx.managers::CursorManager$/showCursor()[C:\dev\flex_201_ja\sdk\frameworks\mx\managers\CursorManager.as:166]
...

Expected Results: mouse cursor should be toggled visible and invisible on repeadetly clicking the stage.

Workaround: none

Platform: found on Mac, similar behavior suspected on Windows.
