Ok here is a hint which could indicate to the root of your problems,
apparently GAE has session handling disabled you have to enable it.
<sessions-enabled>true</sessions-enabled
in the appeninge-web.xml file to enable it.
Also some links indicate you should only use state saving client.

Ok this could be an indication to the viewstate issue you are facing
http://java.dzone.com/news/jsf2-configuration-google-app
seems like GAE has its fair share of problems or the underlying
container of GAE that is.
All I can say, if it is just for learning purposes try to program your
program locally and when it comes to deployment find a hoster which
allows you to use your own app stack. As for the ajax stuff, I will give
GAE a try as I said, but I assume your problem is related to the other
session scope problems GAE seems to have.

Ok I cannot really help with the viewExpired Problem except for that it
indicates a problem on GAEs side.
But I ran your Ajax problem quickly through and for me it works locally
here. So I assume you run into a GAE related issue here as well.
I will do a GAE testsetup as my scarce time permits to run this through,
but I really assume a gae related problem or a deployment related
problem here.
It would be interesting to know if in the ajax case the browser throws
any errors. What does the browser error console say?

Yesterday evening I noticed java.io.InvalidObjectException stopped being
thrown. I don't know why but I hope it is related to switching from
eclipse
to intellij& not due to gae. (I also learned facelets is built into
jsf2 so
a separate jar isn't required.)
I have two new problems which only happen on live gae--not dev gae:
1) I'm testing jsf-basics.zip on
http://www.coreservlets.com/JSF-Tutorial/jsf2/code/.
* open bank-lookup.jsf
* fill in form
* click [Show Current Balance]
* the correct jsf page is displayed
* click chrome's Back
* javax.faces.application.ViewExpiredException is thrown (whether using
client or server state saving):

This doesn't happen if I submit the form with errors, fix them,& click
[Show Current Balance] button:
* open bank-lookup.jsf
* click [Show Current Balance] button
* validation errors are shown (post back)
* correct errors
* click [Show Current Balance] button
* click Back button
2) A simple use of<f:ajax> doesn't update:
<h:selectOneMenu id="menu" value="#{bankingBean.customerId}">
<f:ajax event="change" execute="@this" render="register"/>
<f:selectItems value="#{bankingBean.customerIds}"/>
</h:selectOneMenu>
<h:outputText id="register" value="#{bankingBean.customerId}"/>

I'm a JSF2/myfaces rookie. I have it working w/ Eclipse Helios& gae
Eclipse plugin. When I deploy it& visit my test page, a blank page is
displayed& the log entry is appended to this message. It appears to
be a
session deserialization problem. Thx. for your help.
