JavaFX8: exception when adding items to ObservableList: ConcurrentModificationException

I have an a ChoiceBox that lists months values, when the user choose a value, it execute this lambda expression:

private TableView<IncomeFX> tableIncome;
private ChoiceBox<Month> choiceBoxIncomeMonths;

private ChangeListener<Month> setChoiceBoxIncomeMonthsBehaviour(){
    ChangeListener<Month> months = (ObservableValue<? extends Month> observable, Month oldValue, Month newValue) -> {
            incomesData.clear();
            Year selectedYear = choiceBoxIncomeYears.getSelectionModel().getSelectedItem();
            ObservableList<IncomeFX> temp = incomeManager.getIncomesOf(selectedYear, newValue);
            incomesData.addAll(temp);

    };
    return months;
}

and how i add the listener:

choiceBoxIncomeMonths.getSelectionModel().selectedItemProperty().addListener(setChoiceBoxIncomeMonthsBehaviour());

when I click on the choicebox, i get:

Exception in thread "JavaFX Application Thread" java.util.ConcurrentModificationException

it indicate that the problem is in the line where I call: addAll(temp) how can i solve this ??? thanks

here is how i solve it, it's a bad code i know, but i don't know any other solution, i have to clear it twice or the items will be added like if i didn't clear it, if you do have an other solution i will be happy:

private ChangeListener<Month> setChoiceBoxIncomeMonthsBehaviour(){
    ChangeListener<Month> months = (ObservableValue<? extends Month> observable, Month oldValue, Month newValue) -> {
        if (!lastMonthValuesFired) {
            incomesData.clear();
            Year selectedYear = choiceBoxIncomeYears.getSelectionModel().getSelectedItem();
            ObservableList<IncomeFX> temp = incomeManager.getIncomesOf(selectedYear, newValue);
            ObservableList<IncomeFX> temp2 = FXCollections.observableList(new ArrayList<IncomeFX>());

            for (IncomeFX t : temp) {
                temp2.add(t);
            }
            incomesData.clear();
            incomesData.addAll(temp2);
        }
    };
    return months;
}
