Here's how I did it - I binded the textField's text property with the text property of the cell (bidirectional).

class EditingCell extends TableCell {

        private final TextField mTextField;

        public EditingCell() {

            super();

            mTextField = new TextField();

            mTextField.setOnKeyPressed(new EventHandler() {

                @Override
                public void handle(KeyEvent event) {

                    if( event.getCode().equals(KeyCode.ENTER) )
                        commitEdit((T)mTextField.getText());
                }
            });

            mTextField.focusedProperty().addListener(new ChangeListener() {

                @Override
                public void changed(ObservableValue observable, Boolean oldValue, Boolean newValue) {

                    if( !newValue )
                        commitEdit((T)mTextField.getText());
                }

            });

            mTextField.textProperty().bindBidirectional(textProperty());
        }

        @Override
        public void startEdit() {

            super.startEdit();

            setGraphic(mTextField);
        }

        @Override
        public void cancelEdit() {

            super.cancelEdit();

            setGraphic(null);
        }

        @Override
        public void updateItem(final T item, final boolean empty) {

            super.updateItem(item, empty);

            if( empty ) {
                setText(null);
                setGraphic(null);
            }
            else {
                if( item == null ) {
                    setGraphic(null);
                }
                else {
                    if( isEditing() ) {
                        setGraphic(mTextField);
                        setText((String)getItem());
                    }
                    else {
                        setGraphic(null);
                        setText((String)getItem());
                    }
                }
            }
        }
    }
