JSF and JSTL. :'(

Question

I'm trying to include a "jspx" component if the user has a role, but "c:if" seems not to work.
    <f:view>
    ${submenu}
    ${not empty submenu}
    <c:if test="#{not empty submenu}"><jsp:include page="${submenu}" /></c:if>
   </f:view>The first 2 lines print
mysubmenufile.jspx
true
... other code, not my included file! :'(
Why it doesn't work. I'm using .tag files, and it works fine, but i've to use scriptlet code, like
<% if (cond) { %>lot of unpretty JSF tags<% } %>
Can somebody help me to fix it?

Answer 1

JSTL and JSF don't really play together that well.
I don't know if JSTL tags can understand the #{expr} expr.
Mostly I find it easier to just use JSF.
Any time you include a page, I believe you need to use <f:subview> tags
Why not use that and the rendered attribute to accomplish the same thing:
<f:subview id="submenuView" rendered="#{not empty submenu}">
  <jsp:include page="${submenu}" />
</f:subview>Does that work?
