Karl Sigiscar commented on FLEX-24157:
--------------------------------------
A possible fix would be to modify the implementation of getSystemManager() to
invoke another method when the target is not an IUIComponent. This new method
would search for the closest parent that is an IUIComponent and return it. Then
getSystemManager() would be able to get the systemManager from it.
> RTE - ToolTipManagerImpl - hideTip(), createTip(), positionTip() - when
> getSystemManager() is called with a non-IUIComponent.
