Run code:


package javafx_text_prompt;

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.control.TextField;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class JavaFX_Text_Prompt extends Application{

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

    @Override
    public void start(Stage stage) throws Exception {
        
        VBox vb = new VBox();
        
        final TextField testedTextField = new TextField();
        HBox hb = new HBox();
        
        final TextField tf1 = new TextField();
        Button apply = new Button("Set prompt text");
        apply.setOnAction(new EventHandler<ActionEvent>(){
            @Override
            public void handle(ActionEvent t) {
                testedTextField.setPromptText(tf1.getText());
            }
        });
        
        hb.getChildren().addAll(tf1, apply);
        
        TextField tf2 = new TextField();
        tf2.textProperty().bindBidirectional(testedTextField.promptTextProperty());
        
        vb.getChildren().addAll(new Label("Prompt text issue"), testedTextField, hb, new Label("Current prompt text: "), tf2);
        
        Scene scene = new Scene(vb, 300, 300);
        stage.setScene(scene);
        stage.show();
    }
}


Using the second textField (with pressing button) or the third textField, which's text is bidirectionally binded to PromptText of the first textField, I try to set promptText using different manipulation and I couldn't for a long time (see attached movie).

You can see, that property is set properly, but it is not rendered.

This issue affects on comboBox(editable), passwordField.
