John Gilbert commented on JBSEAM-4898:
--------------------------------------
I have attached 2 sample apps. The jsf2 profile builds the app with seam 2.3 and the jsf1
profile builds the app with seam 2.2. Build the jsf2 profile first and then deploy both
apps at the same time. I am using AS 5.1. The apps have links to each other so you can
switch back and forth. The page and conversation scopes are not working in 2.3.
This is a sample of the facelets the retrieve the template and include view id from scoped
factories.
{code}
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="#{pageScopedTemplate}">
<ui:define name="body">
<ui:include src="#{pageScopedInclude}" />
</ui:define>
</ui:composition>
{code}
Also, the ear build is current configured for expanded mode.
JSF2 Page Scope components are not active on postback

Key: JBSEAM-4898
URL: https://issues.jboss.org/browse/JBSEAM-4898
Project: Seam 2
Issue Type: Bug
Reporter: John Gilbert
Attachments: seam-scope-test-master.zip
Page scoped components are not active on postback during the restore view phase. We have
been doing things like this in JSF 1.2 for years with no trouble.
{code}
<ui:include src="#{pageScopedComponent.viewId}" />
{code}
In JSF 2 the page will render, because the facelet isn't actually complied until the
render phase on a GET. Then on postback the component is not found in the stateful page
scope and then isn't created because the page scope is not active yet.
I have made many attempts to debug this but I have run out of ideas. I'm thinking
this is a bug so I am posting it here. But if someone can give me some fresh ideas on
where to look, I will keep digging.
