commit edit doesn't call setOneditCommit - combobox

Question

I have 1 issue in my project.
I'd like to have a tableColum built with comboBox, and for this i use:
tableColumn.setCellFactory(ComboBoxTableCell.forTableColumn(cbValues));
it works but like DOC says:
By default, the ComboBoxTableCell is rendered as a Label when not being edited, and as a ComboBox when in editing mode.
but i want to see the comboBox every time, so i build this code
tableColumn.setCellFactory(new Callback<TableColumn<Ambientale, Integer>, TableCell<Ambientale, Integer>>() {
#Override
public TableCell<Ambientale, Integer> call(TableColumn<Ambientale, Integer> param) {
return new ComboBoxCell(cbValues);
}
});
and my ComboBoxCell is:
class ComboBoxCell extends TableCell<Ambientale, Integer> implements Callback<Object, Object>{
private ComboBox combo;
public ComboBoxCell() {
combo = new ComboBox();
}
public ComboBoxCell(ObservableList items) {
combo = new ComboBox();
combo.setItems(items);
combo.setOnAction(new EventHandler() {
#Override
public void handle(Event event) {
System.out.println(" it's works");
commitEdit((Integer)combo.getSelectionModel().getSelectedItem());
}
});
}
#Override
public void updateItem(Integer item, boolean empty) {
super.updateItem(item, empty);
if (empty) {
setText(null);
setGraphic(null);
} else {
combo.getSelectionModel().select(item);
setGraphic(combo);
setContentDisplay(ContentDisplay.CENTER);
}
}
#Override
public Object call(Object param) {
return new ComboBoxCell();
}
}
the issue is here!
class ComboBoxCell extends TableCell<Ambientale, Integer> implements Callback<Object, Object>{
private ComboBox combo;
public ComboBoxCell() {
combo = new ComboBox();
}
public ComboBoxCell(ObservableList items) {
combo = new ComboBox();
combo.setItems(items);
combo.setOnAction(new EventHandler() {
#Override
public void handle(Event event) {
System.out.println(" it's works");
commitEdit((Integer)combo.getSelectionModel().getSelectedItem());
}
});
}
#Override
public void updateItem(Integer item, boolean empty) {
super.updateItem(item, empty);
if (empty) {
setText(null);
setGraphic(null);
} else {
combo.getSelectionModel().select(item);
setGraphic(combo);
setContentDisplay(ContentDisplay.CENTER);
}
}
#Override
public Object call(Object param) {
return new ComboBoxCell();
}
}
commitEdit(...) doesn't call:
tableColumn.setOnEditCommit(new EventHandler<TableColumn.CellEditEvent<Ambientale, Integer>>() {
#Override
public void handle(TableColumn.CellEditEvent<Ambientale, Integer> t) { //aggiornare database cella singola
System.out.println("not called");
//other stuffs
}
});
Can you help me please.

It works, i don't know why but it works.
i've added this on my ComboBoxCell
combo.focusedProperty().addListener(new ChangeListener<Boolean>() {
#Override
public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
if (newValue) {
getTableView().edit(getIndex(), getTableColumn());
} else {
commitEdit((Integer)combo.getSelectionModel().getSelectedItem());
}
}
});
