[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3254) <s:selectItems> broken in NumberGuess example

[Pete Muir (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-3254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12424582#action_12424582 ] 

Pete Muir commented on JBSEAM-3254:
-----------------------------------

I had a look, it appears that the JSP page is setting a ValueExpressionLiteral for the #{numberGuess.possibilities} which therefore means that it's sets the String #{numberGuess.possibilities} on the select items instance.

Stan, any idea why this would happen?

> 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> ?
