Ok Ken, so far I have setup my testproject and on ajax I run into the
same crypto exception you have been reporting (state saving method
server) this points towards a bug in the non ajax part somewhere, I will
keep you informed about my results.

Ok another hint, there is a config param which has to be set to prevent
the crypto exception which you face:
see https://issues.apache.org/jira/browse/MYFACES-2606

I use both of those.
I've started playing with wicket because Gavin recommends JSF or wicket
(both have component models). wicket doesn't appear to have active
component
libs like richfaces, primefaces, icefaces.
I'm surprised that richfaces adores mojarra. The lists
http://java.net/projects/javaserverfaces/lists have low activity. Issues
http://java.net/jira/browse/JAVASERVERFACES/ seem to get resolved.
I can only dream of a framework:
* Reliable on gae.
* Several component lib developers conforming to an open look&feel std
like
nimbus.
* Client-side validation first to avoid server load& bandwidth for silly
mistakes like not filling in a required field.

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}"/>

session deserialization problem. Thx. for your help.
