Description

FocusManager Null pointer exception occurs.

This:
public function getNextFocusManagerComponent(
backward:Boolean = false):IFocusManagerComponent

{ return getNextFocusManagerComponent2(backward, fauxFocus).displayObject as IFocusManagerComponent; }

Must be rewritten as:

public function getNextFocusManagerComponent(
backward:Boolean = false):IFocusManagerComponent

{ const focusInfo:FocusInfo = getNextFocusManagerComponent2(backward, fauxFocus); return focusInfo ? focusInfo.displayObject as IFocusManagerComponent : null; }
