Code to reproduce:

public class TestApplicaton extends Application {

    public static void main(final String[] args) {
    launch(args);
    }

    @Override
    public void start(final Stage primaryStage) {
    primaryStage.setTitle("Hello!");

    final StackPane root = new StackPane();

    final JFXSnackbar snackbar = new JFXSnackbar(root);

    final Button btn = new Button();
    btn.setText("Show snackbar");
    btn.setOnAction(event -> {
        final JFXSnackbarLayout content = new JFXSnackbarLayout("Hello World!", "Hide", e -> snackbar.close());
        snackbar.enqueue(new SnackbarEvent(content, Duration.seconds(10)));
    });

    root.getChildren().add(btn);
    final Scene scene = new Scene(root, 400, 250);
    root.getStylesheets().add(JFoenixResources.load("css/jfoenix-design.css").toExternalForm());
    primaryStage.setScene(scene);

    primaryStage.show();
    }
}

Tested with version 8.0.9

Kind regards

Hi there,

I'm still experiencing this issue, even on version 8.0.10. The proposed test code fails after the event duration time: in that case, 10s. The problem also happens on 8.0.9. This is the stack trace.

Additionally, implementing the workaround proposed by @sawaYch on the another related issue also does not completely solve the problem, as it makes the second event invisible.

Am I doing something wrong? Thank you all :)
