單擊“添加約會”按鈕時，會彈出新表單，但 DatePicker 為空（應填充 LocalDate.now()），并且周六/周日日期均未禁用。嘗試在 Initialize 和啟動新場景的方法中調用設置方法。無論我將它放在一個或另一個或兩個中，它都不起作用。請告知我做錯了什么。謝謝。顯示 DatePicker 值空白且日歷中沒有禁用日期的圖像。package gci.controllers.dialogs;import gci.App;import gci.models.Appointment;import gci.utilities.CustomerDAO;import java.io.IOException;import java.net.URL;import java.sql.SQLException;import java.time.*;import java.util.*;import java.util.logging.*;import java.util.stream.*;import javafx.collections.*;import javafx.event.ActionEvent;import javafx.fxml.*;import javafx.scene.*;import javafx.scene.control.*;import javafx.scene.layout.*;import javafx.stage.*;import javafx.util.*;public class AddAppointmentController implements Initializable {    @FXML private ChoiceBox<String> nameChoiceBox;    @FXML private ChoiceBox<String> typeChoiceBox;    @FXML private ChoiceBox<String> timeChoiceBox;    @FXML private Label titleLabel;    @FXML private Label copyrightLabel;    @FXML private Button saveButton;    @FXML private Button cancelButton;    @FXML private DatePicker datePicker;    private final CustomerDAO dao = new CustomerDAO();    private Stage stage;    private static final Region modal = new Region();    @Override    public void initialize(URL url, ResourceBundle rb) {        initApptChoiceBoxes();        setDatePicker();        setCopyright();        modal.setStyle("-fx-background-color: #00000099;");    }    private void initApptChoiceBoxes() {        try {            nameChoiceBox.setItems(dao.retrieveAll().stream().map(m -> m.getName())                .collect(Collectors.toCollection(FXCollections::observableArrayList)));        } catch (SQLException ex) {            Logger.getLogger(AddAppointmentController.class.getName()).log(Level.SEVERE, null, ex);        }        typeChoiceBox.setItems(FXCollections.observableArrayList("In-Person", "Phone", "WebMeeting"));    }    }
