Bug demonstration: set autoBack=false and listen on the backButton for UIButton.CLICKED event. firstList function does not get called.

Not a bug - (just an inconsistency in the way my component work).

The backButton and rightArrow don't dispatch a UIButton.CLICKED event. They dispatch MouseEvents.

(But, The rightButton is a subclass of UIButton, and dispatches UIButton.CLICKED)

So change the listener to detect MouseEvent.MOUSE_UP ... and this example works.
