Stan Silvert commented on JBSEAM-3254:

To be more clear, I think it should look like this:

<taglib xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"

<tlib-version>2.1</tlib-version> corresponds to Seam 2.1.  

Tomcat/Jasper will look at <taglib ... version="2.1"> to know how it needs to treat the <deferred-value>.

>                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3254
>             Project: Seam
>          Issue Type: Bug
>          Components: JSF Controls
>    Affects Versions: 2.1.0.A1
>            Reporter: Stan Silvert
>            Assignee: Pete Muir
>             Fix For: 2.1.0.BETA1
> When you run the Numberguess example, you get to a point where the numberGuess page switches to showing a dropdown of choices:
>         <h:selectOneMenu value="#{numberGuess.currentGuess}" id="selectGuessMenu" required="true"
>                        rendered="#{(numberGuess.biggest-numberGuess.smallest) le 20 and (numberGuess.biggest-numberGuess.smallest) gt 4}">
>           <s:selectItems value="#{numberGuess.possibilities}" var="i" label="#{i}" />
>         </h:selectOneMenu>
>         <h:selectOneRadio value="#{numberGuess.currentGuess}" id="selectGuessRadio" required="true"
>                        rendered="#{(numberGuess.biggest-numberGuess.smallest) le 4}">
>           <s:selectItems value="#{numberGuess.possibilities}" var="i" label="#{i}" />
>         </h:selectOneRadio>
> At that point, you will get an IllegalArgumentException as similar to the last comment of JBSEAM-880:
> java.lang.IllegalArgumentException: Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectOne(selectGuessMenu).  Found java.lang.String.
> 	com.sun.faces.renderkit.RenderKitUtils.getSelectItems(RenderKitUtils.java:357)
>  If I add a noSelectionLabel to each <s:selectItems> then the IllegalArgumentException will go away, but the values do not populate the dropdown.
> It looks like there might be something wrong deep inside <s:selectItems> ?
