BorderPanes - JavaFX Scene Builder - Scrollbar down button not visibel - javafx

Question

I have a small problem with the position / visibility of the lower scrollbar button of the BorderPanes (EBMTableView) - JavaFX Scene Builder
I want that if I minimize the window, the bottom scrollbar button is always visible.
Thank you very much

Problem Solved, just change the first BorderPane Params like this ->
<BorderPane maxHeight="0" maxWidth="0"
minHeight="0" minWidth="0" prefHeight="0"
prefWidth="1230.0" xmlns="http://javafx.com/javafx/8.0.111"
xmlns:fx="http://javafx.com/fxml/1"
