yes, that's what appear's to be happening.

You are probably only seeing the event when the TableView's internal ScrollPane doesn't consume it.

Re: Scroll events fired in TableView although there is nothing to scroll
Hi, yes, I just now realized that setOnScroll is Node API and not TableView so I obviously sent my Mail too early. Sorry about the noise. Another observation, though: The onscroll-eventhandler is not called when the tableview actually does scroll. It does fire again, when I reach one end of the data and keep using scroll gestures.
