There are some significant interoperability issues between JSF 1.0/1.1 and
JSTL -- some of which have been addressed in JSF 1.2. But there is a more
fundamental design issue here ... you're trying too hard :-). Consider this
instead:
<h:selectOneMenu id="status" value="#{ProjectEdit.status}">
<f:selectItems value="#{projects.statusList}"/>
</h:selectOneMenu>
where the getStatusList() method of your "projects" managed bean returns an
array or list of SelectItem instances. There's no reason for you to have to
do the iteration in the view tier.
