Error while working with JSF SelectOneMenu and JSTL forEach Tag

[Saravanan Vijayappan]

Hello,

I am new to JSF. I have set up few things in ArrayList in my contextListener as like below

ServletContext context=event.getServletContext();
List list=new ArrayList();
list1.add("Honda");
list1.add("Mazda");
list1.add("eClipse");
context.setAttribute("carList", list)

I just wanted to display the list in my JSF page, I wrote the below statements in my JSF page


<h:selectOneMenu value="{com.carSelection}">
<c:forEach var="car" items="${applicationScope.carList}" >
<f:selectItem itemLabel="${car}"/>
</c:forEach>
</h:selectOneMenu>

I am getting the below exception

org.apache.jasper.JasperException: /pages/protected/cmt/index.jsp(23,2) According to TLD or attribute directive in tag file, attribute itemLabel does not accept any expressions
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)

Could some one help to solve this error (Or) How should I display from my applicationScope list into MenuItems ?

You are mixing up JSTL and JSF tags. Not sure if this will work.
One way to do this is to use f:selectItems instead of c:foreach and f:selectItem, but you should create a SelectItem List from your carsList.
Another way if you are using Tomahawk is to use t:selectItems in which case you can directly use carsList. Tomahawk will convert the list to SelectItem list for you. Check out the MyFaces documentation and the wiki page.

 
 
<h:selectOneMenu value="{com.carSelection}">
<f:selectItems var="#{applicationScope.carsSelectItemList}" />
</h:selectOneMenu>
 
or 
 
<h:selectOneMenu value="{com.carSelection}">
<t:selectItems var="#{applicationScope.carList}" />
</h:selectOneMenu>

Thank you for your reply.

Unfortunately, In JSF 1.2 RI, the UI <f:selectItems> does not have the attribute "var", so, the below code does not work. I think, this can't be done JSF1.2 UI. As you suggested, I might need to add Tomahawk into my application. Please let me know if there are any other solutions. I am using richfaces with JSF1.2 RI

===============================================================
<h:selectOneMenu value="{com.carSelection}">
<f:selectItems var="#{applicationScope.carsSelectItemList}" />
</h:selectOneMenu>

or

<h:selectOneMenu value="{com.carSelection}">
<t:selectItems var="#{applicationScope.carList}" />
</h:selectOneMenu>

I meant to say 'value' not 'var'. Try it again now.
