How do I populate h:selectOneMenu with a sequence of numbers?

Question

Hi,
I would think this would be simple, but I cannot figure out how to get it to work for the life of me. I want to have a drop down list box populated with sequential numbers. I tried this, but it fills it with blanks (I think that's what it did, I tried so many things I am forgetting what did what):
<h:selectOneMenu value="#{query.response}">
<c:forEach var="i" begin="1" end="31">
<f:selectItem itemLabel="#{i}" itemValue="#{i}"/>
</c:forEach>
</h:selectOneMenu>
I got it to fill with zeros if I say "#{0 + i}".
I am new to JavaServer Faces, but I think it's because the loop happens early, and the # expression is deferred and happens after "i" no longer exists.
How do I accomplish this? Any help is appreciated. I searched the net far and wide and could not find a solution (which seems weird, I would think this would be a common thing to want to do).
Thanks.

Use f:selectItems and let the backing bean return a List<SelectItem> with the desired values.
<h:selectOneMenu value="#{myBean.selectedItem}">
    <f:selectItems value="#{myBean.selectItems}" />
</h:selectOneMenu>
private Integer selectedItem; // + getter + setter.
private List<SelectItem> selectItems; // + getter.
public MyBean() {
    fillSelectItems();
private void fillSelectItems() {
    selectItems = new ArrayList<SelectItem>();
    for (int i = 1; i <= 31; i++) {
        selectItems.add(new SelectItem(new Integer(i)));
}PS: if you want to create kind of a calendar selection, rather look for existing components such as Tomahawk Calendar: [http://myfaces.apache.org/tomahawk/calendar.html].
