JavaFX TableView using FX Objects

Question

I am trying to put a stack panel in my TableView and I keep getting errors.

I suspect it is my lack of understanding of creating the Cell Value Factory.

My Code looks like:

TableColumn obj = new TableColumn("Func " + i);
        final int index = i;
        obj.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<ObservableList<String>, String>, TableCell<ObservableList<String>, String>>() {



            @Override
            public TableCell<ObservableList<String>, String> call(final CellDataFeatures<ObservableList<String>, String> cdf) {
                if (index + 2 >= cdf.getValue().size()) {
                    return null;
                }
                //return new SimpleStringProperty(cdf.getValue().get(index + 2));
                return new TableCell<ObservableList<String>, String>(){
                    Label funcLbl = new Label(cdf.getValue().get(index+2));
                    StackPane sp = new StackPane();


                    @Override
                    protected void updateItem(String item, boolean empty) {
                        super.updateItem(item, empty); //To change body of generated methods, choose Tools | Templates.
                        sp.getChildren().add(funcLbl);
                        setGraphic(sp);
                    }
                };
            }
        });
        obj.setMinWidth(100);
        this.getColumns().add(obj);

And the Error I am getting is

SEVERE: javafx.scene.control.Control loadSkinClass Failed to load skin 'StringProperty [bean: PinTable[id=null, styleClass=table-view], name: skinClassName, value: com.sun.javafx.scene.control.skin.TableViewSkin]' for control PinTable[id=null, styleClass=table-view]

I am trying to convert from using a

public ObservableValue<String> call(CellDataFeatures<ObservableList<String>, String> cdf)

and only returning a SimpleStringProperty to returning a TableCell<ObservableList<String>, String> that has a StackPane as its content with the String held in a Label (I want to create actions based on clicking on the stack pane).

Any help on understanding the transition would be great!

I did something similar in an answer here.

CellValueFactory is to populate data in cells of column from model object ..

Example :

lastNameCol.setCellValueFactory(new PropertyValueFactory<Person,String>("lastName"));

If you want to render data in all cells of table column then you must use cellFactory.
