    <p>I am trying to put a stack panel in my <code>TableView</code> and I keep getting errors.</p> <p>I suspect it is my lack of understanding of creating the Cell Value Factory.</p> <p>My Code looks like:</p> <pre><code>TableColumn obj = new TableColumn("Func " + i); final int index = i; obj.setCellValueFactory(new Callback&lt;TableColumn.CellDataFeatures&lt;ObservableList&lt;String&gt;, String&gt;, TableCell&lt;ObservableList&lt;String&gt;, String&gt;&gt;() { @Override public TableCell&lt;ObservableList&lt;String&gt;, String&gt; call(final CellDataFeatures&lt;ObservableList&lt;String&gt;, String&gt; cdf) { if (index + 2 &gt;= cdf.getValue().size()) { return null; } //return new SimpleStringProperty(cdf.getValue().get(index + 2)); return new TableCell&lt;ObservableList&lt;String&gt;, String&gt;(){ 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); </code></pre> <p>And the Error I am getting is</p> <pre><code>SEVERE: javafx.scene.control.Control loadSkinClass Failed to load skin 'StringProperty [bean:

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
