I am trying to use JavaFX 8's DatePicker with disabling the days that are not in the range [today, today + 1 year], similar to [the example in the official tutorial][1]. Here is the code:

**sample.fxml:**

    <?import javafx.scene.layout.GridPane?>
    <?import javafx.scene.control.DatePicker?>
    <GridPane fx:controller="sample.Controller"
              xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10">
    
        <DatePicker fx:id="dpDate"/>
    
    </GridPane>

**Main.java:**

    package sample;
    
    import javafx.application.Application;
    import javafx.fxml.FXMLLoader;
    import javafx.scene.Parent;
    import javafx.scene.Scene;
    import javafx.stage.Stage;
    
    public class Main extends Application {
    
        @Override
        public void start(Stage primaryStage) throws Exception{
            Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
            primaryStage.setTitle("Hello World");
            primaryStage.setScene(new Scene(root, 300, 275));
            primaryStage.show();
        }
    
    
        public static void main(String[] args) {
            launch(args);
        }
    }

**Controller.java:**

    package sample;
    
    import javafx.fxml.FXML;
    import javafx.fxml.Initializable;
    import javafx.scene.control.DateCell;
    import javafx.scene.control.DatePicker;
    import javafx.util.Callback;
    import javafx.util.StringConverter;
    
    import java.net.URL;
    import java.time.LocalDate;
    import java.time.chrono.HijrahChronology;
    import java.time.format.DateTimeFormatter;
    import java.util.ResourceBundle;
    
    public class Controller implements Initializable
    {
     private final DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
    
     @FXML private DatePicker dpDate;
    
     @Override
     public void initialize(URL location, ResourceBundle resources)
     {
     Callback<DatePicker, DateCell> dayCellFactory = dp -> new DateCell()
     {
     @Override
     public void updateItem(LocalDate item, boolean empty)
     {
     super.updateItem(item, empty);
    
     if(item.isBefore(LocalDate.now()) || item.isAfter(LocalDate.now().plusYears(1)))
     {
     setStyle("-fx-background-color: #ffc0cb; -fx-text-fill: darkgray;");
     setDisable(true);
     }
     }
     };
    
     StringConverter converter = new StringConverter<LocalDate>()
     {
     @Override
     public String toString(LocalDate date)
     {
     if(date != null) return dateFormatter.format(date);
     else return "";
     }
    
     @Override
     public LocalDate fromString(String string)
     {
     if(string != null && !string.isEmpty())
     {
     LocalDate date = LocalDate.parse(string, dateFormatter);
    
     if(date.isBefore(LocalDate.now()) || date.isAfter(LocalDate.now().plusYears(1)))
     {
     return dpDate.getValue();
     }
     else return date;
     }
    
     return null;
     }
     };
    
     dpDate.setDayCellFactory(dayCellFactory);
     dpDate.setConverter(converter);
     dpDate.setPromptText("dd/MM/yyyy");
     dpDate.setValue(LocalDate.now());
     dpDate.setChronology(HijrahChronology.INSTANCE);
     }
    }

This example works (i.e. user cannot select out of the range) only if I remove the last line `dpDate.setChronology(HijrahChronology.INSTANCE);` and leave it with default `IsoChronology`.

I have tried to consume the click event inside `updateItem()`:

    @Override
public void updateItem(LocalDate item, boolean empty)
{
super.updateItem(item, empty);
        
if(item.isBefore(LocalDate.now()) || item.isAfter(LocalDate.now().plusYears(1)))
{
setStyle("-fx-background-color: #ffc0cb; -fx-text-fill: darkgray;");
setDisable(true);

addEventFilter(MouseEvent.MOUSE_CLICKED, e -> e.consume());
}
}

It works on the current month (the days before today cannot be selected). But if I go to the next months, it prevents the user from selecting a day from the permitted range.

Definitely this is a bug. Is there a workaround? How can I access the date picker popup? Maybe I can attach a listener to the button that change the month page, and then iterate over all the say cells and disable the out-of-range days manually.
