ComboBox with integer values

I have a comboBox on the xpage associated with the Number field. The code used to populate the SelectItem values ​​for the combo is in a managed bean that looks like this:

/*
 * Returns last year, current year and next year as List<SelectItem>
 * For use with comboBox selection values
 */
public List<SelectItem> getYearSelectItems() {
    int thisYear = Calendar.getInstance().get(Calendar.YEAR);
    List<SelectItem> selectItems = new ArrayList<SelectItem>();
    selectItems.add(new SelectItem(new Integer(thisYear - 1), new Integer(thisYear - 1).toString()));
    selectItems.add(new SelectItem(new Integer(thisYear), new Integer(thisYear).toString()));
    selectItems.add(new SelectItem(new Integer(thisYear + 1), new Integer(thisYear + 1).toString()));

    for(int i = 1; i < selectItems.size(); i ++) {
        System.out.println(new Integer(i).toString() + ": " + selectItems.get(i).getValue().getClass());
    }
    return selectItems;
}

As you can see, I am printing class names for SelectItem values ​​for the console for debugging. The class name specified in the console is java.lang.Integer, so the part is definitely correct.

Combobox uses a numerical converter to match a field in a form, only an integer.

The problem is that validation fails with this configuration.

, <xp:convertNumber> SelectItem(<Integer>, <String>) - . Double .

:

/*

 * For use with comboBox selection values
 */
public List<SelectItem> getYears() {
    int thisYear = Calendar.getInstance().get(Calendar.YEAR);
    List<SelectItem> years = new ArrayList<SelectItem>();
        years.add((new SelectItem(new Double(thisYear - 1), new Integer(thisYear - 1).toString())));
        years.add(new SelectItem(new Double(thisYear), new Integer(thisYear).toString()));
        years.add(new SelectItem(new Double(thisYear + 1), new Integer(thisYear + 1).toString()));

    }
    return years;

Number Number Integer, integerOnly=true . , NumberField Bean Object as variable sysout (newValue.class) getter & setter.

Integer vartype, Invalid Argument Numberfield. .

Bean ( ):

private static Map<String,Integer> years;

}

public void yearChanged(ValueChangeEvent e){
    System.out.println("event Start " + selectedYear);
    selectedYear = years.get(e.getNewValue());//Set new Value to field
    System.out.println("event End " + selectedYear);
}
