JavaFX style class won't refresh

I'm adding a style class to an node if it's selected and then remove it if I select other item. Even if I remove the style class the style wont refresh so it wont go back to normal state:


but the style will stay the same as class selected

This is a bug. It is reported here Removal of hovered style class, does not update styling. You may want to vote and watch it. As a workaround you should override css rules you touched/changed to be the same as default ones. Demo:

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBoxBuilder;
import javafx.stage.Stage;

public class StyleDemo extends Application {

    public void start(Stage primaryStage) {
        final Label lbl = new Label("Style Me");
        lbl.getStyleClass().add("style1"); // initial style

        Button btn = new Button("Change the style");
        btn.setOnAction(new EventHandler<ActionEvent>() {

            public void handle(ActionEvent arg0) {

        StackPane root = new StackPane();
        root.getChildren().add(VBoxBuilder.create().spacing(20).children(lbl, btn).build());
        Scene scene = new Scene(root, 300, 250);

    public static void main(String[] args) {

and the style.css is:

.style1 {
    -fx-text-fill: red;
    -fx-border-color: green;
    -fx-font-size: 20;

.style2 {
    -fx-text-fill: blue;
    -fx-border-color: red;
    -fx-font-size: 15;
    -fx-underline: true;

when the button is clicked the initially added style1 is removed and the style2 is added.
