JSF multiple views limit - jsf

Question

I've created a web application that opens up pages inside an iFrame on the main page. Each iFrame is viewable via a tab on the page and uses JSF2.2 with Mojarra view state beans to populate the page.
This works fine when I open up something under 10 tabs; but when I try to open up more, the beans that held the first pages are destroyed and get recreated when I make any calls to the bean thus losing any prior changes the user may have made.
I'm using Apache Tomcat 7 with Catalina, and this issue is happening on my XP and Windows Server 2008 machines.
This is my current web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

</context-param>
<context-param>
<param-name>com.sun.faces.numberOfLogicalViews</param-name>
<param-value>30</param-value>
</context-param>
</web-app>
I've also tried setting this environment variable thinking that it might be a memory limit on tomcat's end, but it didn't make a difference
set JAVA_OPTS=-Dfile.encoding=UTF-8 -Xms128m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=256m
Any help would be appreciated!

Answer 1

You've there just a severe design error. To include server side page fragments, you're using 90's style iframes instead of true server side include components. Each iframe has its own view state and won't reuse the main document's view state. Just replace all those <iframe> things by <ui:include> and world should be well.
