ControlsFX CheckComboBox

[Rey Rodriguez]

// create the data to show in the CheckComboBox 
ObservableList<String> strings = FXCollections.observableArrayList();
 for (int i = 0; i <= 100; i++) {
     strings.add("Item " + i);
 }
 
 // Create the CheckComboBox with the data 
CheckComboBox<String> checkComboBox = new CheckComboBox<String>(strings);

When selecting a items give this error:
