Dynamic ui:include

Question

I wrote this question:
https://stackoverflow.com/questions/8589315/jsf2-dynamic-template

but BalusC and casperOne told that i wrote it bad so I try to explain better my problem.
As I wrote, I have my project in this structure:

in web root 3 xhtml pages: index, include and welcome;
all others xhtml pages in a subfolder into WEB-INF called jsf.

I suppose that it is a good thing, but I create all pages using the netbeans' wizard "New JSF Pages From Entity Classes..." and for using this structure with this wizard, I can't link directly the xhtml pages saved into jsf forlder, as created by wizard, and I created the include.xhtml and modify all methods for redirecting to this page, as I will explain later, the include.xhtml contains only this code:

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
   xmlns:ui="http://java.sun.com/jsf/facelets"
   xmlns:f="http://java.sun.com/jsf/core"
   xmlns:h="http://java.sun.com/jsf/html">


   <h:head>
   </h:head>
   <h:body>
      Utente connesso:<h:outputText value="#{userBean.cognome}"/>

      <h:outputText value="#{userBean.nome}"/>
      <br/&gr;

      <ui:include src="#{logicBean.pageIncluded}"/>

   </h:body>
</html>

As I said, I modified all methods to call action method in LogicBean that contains the setPageIncluded and return "include.xhtml" something like this:
PageController.java:

public void prepareList() {
    recreateModel();
    LogicBean l = (LogicBean) FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("logicBean");
    l.action(url+"List.xhtml");
}

LogicBean.java:

public String action(String value) {
   setPageIncluded(value);
   return "include";
}

Now this code works quite well and I can navigate from to all pages.
There is only a problem, the bean LogicBean is stored into the session!
This means that if I tried to open a new windows for navigate different part of the project in the same time I can't do that because LogicBean can contains only a single value of pageInclude!

I tried to use the ViewScope but or I don't understand how it works, and in this case it isn't useful, or I wrong something and it doesn't work properly!
Some one can help me?

I found this question that seems could help me: dynamic ui:include with el-expression?
but I don't know if it could help and how modify the c:forEach and action method for using it for my situation!

I hope that this time I explain better my problem and, if it so, I thank you for help!

For what I read here you would like to have a state per browser tag, not per browser, right? — Adrian Mitev, Jan 10 '12 at 13:21
@ Adrian Mitev : if you for "state" mean something like session but not shared between browser's windows or browser's tab,yes you're right! — Filippo1980, Jan 10 '12 at 14:03
@ Adrian Mitev : for now Glassfish 3.1, but it could change for JBoss (i don't know which version) why? it could help me? — Filippo1980, Jan 11 '12 at 10:02

You use a JEE6 certified server, so you can use CDI for bean management. There is a CDI extension library called MyFaces CODI that has a Window scope bundle in it and you can use it to scope your beans instead of using session scope. This will solve your problem with the bean scoping.

You have to annotate your bean with @WindowScoped when using CODI – Adrian Mitev Jan 11 '12 at 15:54
