Listening to a change in focus on the TextField is one way.. I added a listener to the focusedProperty of the textField. The example from Oracle didn't include this. [edit - here is a link to another question that has a different approach UITableView - Better Editing through Binding? ]

private void createTextField() {
        textField = new TextField(getItem());
        textField.setMinWidth(this.getWidth() - this.getGraphicTextGap() * 2);

        // Detect a change in focus on the text field.. If we lose the focus we take appropriate action
        textField.focusedProperty().addListener(new ChangeListener() {
            public void changed(ObservableValue observable, Boolean oldValue, Boolean newValue) {
                if(!newValue.booleanValue())
                    commitEdit(textField.getText());
            }
        } );
        textField.setOnKeyReleased(new EventHandler() {
            @Override public void handle(KeyEvent t) {
                if (t.getCode() == KeyCode.ENTER) {
                    commitEdit(textField.getText());
                } else if (t.getCode() == KeyCode.ESCAPE) {
                    cancelEdit();
                }
            }
        });
    }
