Bug when using a Map for SelectItems?

Question

Hi there,
I think I found a pretty bad bug.... I don't think this behaviour is intended:
I create a selectOneListbox which uses a map for storing the selectItems. The property holding the value is type compatible with the value in the map. When the component is shown, the wrong item is selected (ie NOT The one that is returned by the value property). If I use SelectItem[] for the selectItems, it works. Here is some sample code:
The methods in the bean (managed bean with the name helloBean). The value property always returns 12 .....
  public Map getItems(){
    Map map = new HashMap();
    map.put("Hello_11", new Integer(11));
    map.put("Hello_12", new Integer(12));
    map.put("Hello_13", new Integer(13));
    map.put("Hello_14", new Integer(14));
    return map;
  public SelectItem[] getItems2(){
    SelectItem[] items = {
        new SelectItem(new Integer(11), "Hello_11"),
        new SelectItem(new Integer(12), "Hello_12"),
        new SelectItem(new Integer(13), "Hello_13"),
        new SelectItem(new Integer(14), "Hello_14"),       
    return items;
  public Integer getValue(){
    return new Integer(12);
  }..... here is how the selectOneListboxes are initialized ......
<h:form id="helloForm">
        <h:selectOneListbox size="1" value="#{helloBean.value}">
          <f:selectItems value="#{helloBean.items}"/>
        </h:selectOneListbox>
        <h:selectOneListbox size="1" value="#{helloBean.value}">
          <f:selectItems value="#{helloBean.items2}"/>
        </h:selectOneListbox>
</h:form>.... so both boxes refer to the same value property but their selectItems are taken from a map and a SelectItem[] array respectively. I would expect to see in both boxes the text "Hello_12", BUT:
<select name="welcomeForm:_id0" size="1">     
     <option value="14">Hello_14</option>
     <option value="12">Hello_12</option>
     <option value="13">Hello_13</option>
     <option value="11">Hello_11</option>
</select>
<select name="welcomeForm:_id2" size="1">     
     <option value="11">Hello_11</option>
     <option value="12" selected="selected">Hello_12</option>
     <option value="13">Hello_13</option>
     <option value="14">Hello_14</option>
</select>as you can see, only for the array the correct value is initially selected.
Can anyone confirm this is a bug - or - what i would prefer tell me how to get around this?
Thanks a lot!

If getValue returns "12" (a String value), the situation is reversed.
See the page 9-31 of the specification. It says:
4. A java.util.Map where the keys are
converted to Strings and used as labels, and
the corresponding values are converted to
Strings and used as values for newly
created javax.faces.model.SelectItem
instances. The instances are created in the
order of the iterator over the keys provided
by the Map.
