[Trinidad] Use tr:iterator var in JSTL tag

Hi
 
I'm trying to do something like that
 
<tr:iterator value="#{projects}" var="project">
    <c:choose>
        <c:when test="${project.foo()}">
        </c:when>
    </c:choose>
</tr:iterator>
 
But I can't access to project var from JSTL tags. Somebody knows a way to access this var from JSTL tags?
 
Thanks

You can't.

In JSF, *first* a component tree is built, *then* the component tree is
rendered. JSP/JSTL tags run during the "build" phase, but  tr:iterator
executes its contents during the "render" phase.

In general, you should avoid c:if and c:choose completely when writing
JSF applications. Use the JSF "rendered" attribute available on each
component instead.

See here for a general overview of JSF:

Simon
