Should this also work in Application.handleException()?  I've got this:

public WOResponse handleException(Exception anException, WOContext aContext) {
AMErrorPage errorPage = (AMErrorPage) pageWithName(AMErrorPage.class
.getName(), aContext);
errorPage.setPageType(AMErrorPage.EXCEPTION);
if (AjaxUtils.isAjaxRequest(aContext.request())) {
AjaxUtils.redirectTo(errorPage);
return errorPage.context().response();
}
return errorPage.generateResponse();
}

Throwing an exception from an Ajax action bypasses my AMErrorPage, somehow logs me out of the app, and returns my Main page.  I can't even see how it's occurring.  There's literally nothing in the console beyond a log message from AMErrorPage.setPageType().  Again, this is a slightly different issue than the OP, and I assume your code above was for Application.handleSessionRestorationErrorInContext.

I have the same code (more or less) and it worked the last time that I tested it.  It sounds like there might be some other request getting to the app after the one causing the exception.  Try overridding dispatchRequest and logging out each request.uri().

Looks like there is:

Jan 27 11:49:24 AM[54210] WARN  NSLog  - <er.ajax.AjaxRequestHandler>: Exception occurred while handling request:
java.lang.NullPointerException
Jan 27 11:49:24 AM[54210] INFO  NSLog  - Application.handleException: Handling an Exception:
[2009-1-27 11:49:24 CST] <WorkerThread1> java.lang.NullPointerException

... [Stack trace of my deliberately-generated NPE deleted]

Jan 27 11:49:24 AM[54210] INFO  NSLog  - AMErrorPage.setPageType: pageType = exception
Application.dispatchRequest: URI = /cgi-bin/WebObjects/AM.woa/wo/5.0

That looks unusual (to me).
