Override mx_internal function Error 1004

If you need to override mx_internal function you will encounter Error 1004.

If you include in header would work for call of mx_internal namespace function or variable
import mx.core.mx_internal
use namespace mx_internal;
but in override, wouldn't work.

You will find online Adobe employee Jedi for Adobe Highcouncil have registered bug(2010  and in current year is 2012 Flex SDK 4.6) and advice, that in 99% wouldn't work , "to remove override key word".
Above would fool compiler but would throw run-time error of incompatible override signature.
Now pull you hair.

After not having any hair I found out solution:

public namespace mx_internal = "http://www.adobe.com/2006/flex/mx/internal";



            override mx_internal function updateOrientationState():void
            {
                               
                //super.mx_internal::updateOrientationState();
               
                        
            }
