I've a GridPane with a style class "form"

gridPane.getStyleClass().add("form");

and this style sheet information:

.form {
  -fx-node-hpos: right;
  -fx-node-vpos: bottom;
  -fx-hgap: 20;
  -fx-vgap: 20;
}

If I switch to the style sheet the hgap and vgap works, but -fx-node-hpos and -fx-node-vpos has no effect.
