s:selectItems noSelectionLabel does not generate option value
-------------------------------------------------------------

                 Key: JBSEAM-4654
                 URL: https://jira.jboss.org/browse/JBSEAM-4654
             Project: Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.2.1.CR1
         Environment: JBoss 6 M3
            Reporter: Andrew Wheeler


When a selectOneMenu has no items other than the no selection option it does not render the option value as org.jboss.seam.ui.NoSelectionConverter.noSelectionValue. In this case the there are no values in person.images.

<h:selectOneMenu id="portrait" value="#{person.portrait}">
    <s:selectItems value="#{person.images}" var="i" label="#{i.annotation}" hideNoSelectionLabel="false" noSelectionLabel="Select a portrait..."/>
    <s:convertEntity/>			
</h:selectOneMenu>

This renders:
<select id="person:portraitDecoration:portrait" name="person:portraitDecoration:portrait" size="1">	<option selected="selected">Select a portrait...</option>
</select>

The result is that any form submit causes a java.lang.NumberFormatException with message: "For input string: "Select a portrait..."" 

I have debugged a little and I can see that the converter is not firing when rendering the page. It does however fire for other selectOneMenu items on the page that have one or more items.

A similar and perhaps related issue is referenced in the JBoss Forum.
