Pasted values are duplicated in section Properties -> Style

[tymur-berezhnoi]

I'm using:

Product Version
JavaFX Scene Builder 10.0.0

Build Information
Version 10.0.0
Date: 2018-06-05
Java Version: 10.0.1+10, Oracle Corporation
....
....
Operating System
Mac OS X, x86_64, 10.13.6

whenever I copy a value and paste it to the Properties -> Style I see the value is duplicated in one field: #2b4496#2b4496

For example, I want to use color #2b4496 for style -fx-background-color -> I copy the value #2b4496 somewhere and paste it as value in the scene builder and get the value #2b4496#2b4496. It always happens when I use hot keys for copy/paste in my Mac OS Command+C/Command+V, but it works just fine when I use mouse right click -> copy -> paste.

Actually this seems to be a JavaFX bug.

It can be reproduced on Mac, when there is a system MenuBar with a MenuItem that has an accelerator set to Cmd+V, and a TextField.

Given that the TextField also has an internal key event handler based on the same key combination, both events are processed.

To reproduce:

    @Override
    public void start(Stage stage) {
       TextField textField = new TextField();

        MenuItem paste = new MenuItem("Paste");
        paste.setOnAction(e -> textField.paste());
        paste.setAccelerator(new KeyCodeCombination(KeyCode.V, KeyCombination.META_DOWN));
        Menu menu = new Menu("Edit");
        menu.getItems().add(paste);
        MenuBar menuBar = new MenuBar(menu);
        menuBar.setUseSystemMenuBar(true);

        BorderPane pane = new BorderPane(textField);
        pane.setTop(menuBar);

        Scene scene = new Scene(pane, 300, 200);
        stage.setScene(scene);
        stage.show();
    }

now copy something to the clipboard and paste it using Cmd+V, it will be duplicated.
