Wayne,
I tried to deploy my app in Tomcat to test your theory about JBoss, and it worked. Tomcat's console window does not give any error messages any more, whereas JBoss does. I have tried to find the "bad" jars in JBoss shered lib, but I can't find any JSF-jars there.
One big problem still remains. In both Jboss and Tomcat, the only way to make it work without a thrown exception is to remove ALL subview tags, which contradictory to everything I have read about JSF. This is how the good code looks:
--------------
Main page:
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<html>
<head>
<meta HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=UTF-8" />
<title>MyFaces - the free JSF Implementation</title>
<link rel="stylesheet" type="text/css" href="" />
</head>
<body>
<f:view>
<f:loadBundle basename="org.apache.myfaces.examples.resource.example_messages" var="example_messages" />
<jsp:include page="res2.jsp"/>
</f:view>
</body>
</html>
----------------
Page being included (res2.jsp):
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core" %>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html" %>
<t:div id="subnavigation">
<t:panelNavigation2 id="nav1" layout="list" itemClass="mypage"
activeItemClass="selected" openItemClass="open" >
<t:navigationMenuItems value="#{navigationMenu.panelNavigationItems}" />
</t:panelNavigation2>
</t:div>
----------------
The code above works (with the exception of the warnings about the id:s in JBoss), but when I add the subview tag in either file, I get
javax.servlet.ServletException: Client-id : _id1 is duplicated in the faces tree.
javax.faces.webapp.FacesServlet.service(FacesServlet.java:121)
java.lang.IllegalStateException: Client-id : _id1 is duplicated in the faces tree. org.apache.myfaces.application.jsp.JspStateManagerImpl.checkForDuplicateIds(JspStateManagerImpl.java:241) org.apache.myfaces.application.jsp.JspStateManagerImpl.checkForDuplicateIds(JspStateManagerImpl.java:255)
org.apache.myfaces.application.jsp.JspStateManagerImpl.checkForDuplicateIds(JspStateManagerImpl.java:255)
Could this be the same problem with the overapping JSF-jars in both Tomcat and JBoss, and in that case, which should I remove?
Thank you very much for your help,
Gabor
