SOrry, it is the DateTextFieldDecorator that's causing the problem, and its
code is:
public class DateTextFieldDecorator {
private DateTextField widget;
public DateTextFieldDecorator(DateTextField widget) {
this.widget = widget;
}
public DateTextField from(DateType dateType) {
widget.setRequired(dateType.isRequired());
widget.add(new DatePicker() {
protected boolean enableMonthYearSelection() {
return true;
}
});
widget.setLabel(new Model(dateType.getFieldName()));
return widget;
}
}
