JavaFx FilteredList .setPredicate가 작동하지 않습니다.

Question

이 example과 같은 JavaFx의 텍스트 필드로 TableView에서 필터를 수행하려고합니다.

불행히도 나는 진실한 결과를 얻지 못했습니다. .setPredicate이 FilteredList이면 실행 중이 아니거나 디버그 모드에서 건너 뜁니다.

public class App extends Application { 

TableView tableScanSystemForSnapshots = new TableView<>(); 
private ObservableList<Snapshot> snapshots = FXCollections.observableArrayList(); 
private FilteredList<Snapshot> filteredListSnapshots = new FilteredList<>(snapshots, s -> true); 

public App() { 

} 

@Override 
public void start(Stage primaryStage) throws Exception { 
    //Table View Snapshots 
    tableScanSystemForSnapshots.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE); //make multiple selection in TableView possible 

    //Initialize Columns 
    TableColumn<Snapshot, String> colVmName = new TableColumn<>("VM Name"); 
    TableColumn<Snapshot, String> colSnapshotName = new TableColumn<>("Snapshot Name"); 
    TableColumn<Snapshot, String> colSnapshotDescription = new TableColumn<>("Description"); 
    TableColumn<Snapshot, String> colCreatedTime = new TableColumn<>("created Time"); 
    TableColumn<Snapshot, String> colCreatedBy = new TableColumn<>("created by"); 

    //Initialize ValueFactory - name has to be the same as in Class: Snapshot 
    colVmName.setCellValueFactory(new PropertyValueFactory<Snapshot, String>("vmName")); 
    colSnapshotName.setCellValueFactory(new PropertyValueFactory<Snapshot, String>("snapshotName")); 
    colSnapshotDescription.setCellValueFactory(new PropertyValueFactory<Snapshot, String>("description")); 
    colCreatedTime.setCellValueFactory(new PropertyValueFactory<Snapshot, String>("createdTime")); 
    colCreatedBy.setCellValueFactory(new PropertyValueFactory<Snapshot, String>("createdBy")); 

    //TextField Filter 
    TextField txtFilter = new TextField(); 
    txtFilter.textProperty().addListener(((observable, oldValue, newValue) -> { 
     filteredListSnapshots.setPredicate(s -> { 
      if(newValue == null||newValue.isEmpty()){ 
       return true; 
      } 
      //Compare 
      String lowerCaseFilter = newValue.toLowerCase(); 

      if (s.getVmName().toLowerCase().contains(lowerCaseFilter)){return true;} //Filter matches VM Name 
      if (s.getSnapshotName().toLowerCase().contains(lowerCaseFilter)){return true;} //Filter matches Snapshot Name 
      return false; // Does not match 
     }); 

     SortedList<Snapshot> sortedData = new SortedList<Snapshot>(filteredListSnapshots); 
     sortedData.comparatorProperty().bind(tableScanSystemForSnapshots.comparatorProperty()); 
     tableScanSystemForSnapshots.setItems(sortedData); 
    }));

ObservableList 스냅 샷이 올바르게 채워지지 않았으며 올바르게 수정되었습니다.
