Hi,

please consider the following code. I am expecting that both Labels are visible, because A || B == B || A, but only the second one is visible:

When I replace ReadOnlyBooleanWrapper with SimpleBooleanProperty it works as expected.

Feels like a bug to me?!

import javafx.application.Application;

import javafx.beans.property.BooleanProperty;

import javafx.beans.property.ReadOnlyBooleanWrapper;

import javafx.scene.Scene;

import javafx.scene.control.Label;

import javafx.scene.layout.VBox;

import javafx.stage.Stage;

public class TestApp3 extends Application {

   public static void main(String[] args) {

   launch(args);

  }

   private final BooleanProperty first = new ReadOnlyBooleanWrapper(false);

   private final BooleanProperty second = new ReadOnlyBooleanWrapper(false);

   @Override
   public void start(final Stage stage) throws Exception {

  Label label1 = new Label("first");

  Label label2 = new Label("second");

  label1.visibleProperty().bind(first.or(second));

  label2.visibleProperty().bind(second.or(first));

   first.set(true);

  Scene scene = new Scene(new VBox(label1, label2));

  stage.setScene(scene);

  stage.show();

  }

}
