I tried to implement a load-on-demand TableView with a custom Model. The model implementation returns the "current" rowcount which is higher than the visible rows, until all rows are fully loaded, in the TableView (of course I have some problems with row calculation because I don't know the row height). Independent of the available rows, the vertical scrollbar does not change its values. The table view reads and displays all available rows, if I resize the window/stage - but I can't use the Scrollbar because it uses the "first" instead of the current row count. The navigation with arrow keys is also a problem in that case, because the table doesn't scroll to the selected row.

I tried refresh() and/or requestLayout(), but that did not help.
