I'm creating my own DropDownChoice:
private class WeekdayChoice extends DropDownChoice {
public WeekdayChoice(String id,
IModel model) {
super(id, model, new
Model(new DateFormatSymbols().getWeekdays()));
}
@Override
protected boolean
wantOnSelectionChangedNotifications() {
return true;
}
@Override
protected void
onSelectionChanged(Object newSelection) {
setWeekDayChoice(newSelection);
}
}
... and instantiating it like this:
weeklyLayer.add(weeklyWeekDayChoice = new
WeekdayChoice("weeklyWeekDayChoice",
new
PropertyModel(SubmitForm.this, "weekDayChoice")));
However, before the page even paints I get the exception below - any
ideas?
[ERROR RequestCycle] Exception in rendering component: [MarkupContainer
