To add more info...
I added a bit to make sure it was the timing. I set the cookie scope
manager into a cart subclass and when done using it in the listener
method i called the manager's store method on it. Of course store gets
called again by the system a bit after but by then the cart is not dirty
and so it returns without doing any store stuff. However, the store
works when run earlier than the system defined time. Any way to alter that?
So, where to dig to find what handles calling store on the
StateObjectPersistenceManagers? I'll look more tomorrow but if anyone
has some thoughts on this I'd be interested in hearing it.

I've been trying to setup a new scope for ASO's using cookies. I have
the ASO working fine and injecting into pages.
The problem is by the time the system calls
StateObjectPersistenceManager#store for the cookie manager it seems to
be too late to add cookies to the outgoing response. I checked it
wasn't the ASO by setting a simple cookie like:
cookieSource.writeCookieValue("store", "value"); in the store method
and it doesn't get stored. I'm using CookieSource injected into the
cookie ASO manager.
Does anyone see a way around this problem? Or am I getting it wrong
somehow?
Checking through my logs it shows the listener method beginning, the
cookie scope manager being accessed where it sets a test cookie,
creates the ASO and returns it, work in the listener is done and the
listener method returns, then the cookie scope manager is called to
store the ASO, which it runs through writing another simple cookie as
well as the ASO cookie and returns and finally the servlet's service
method completes. The test cookie in the "get the ASO" method is
available in the browser but the cookies written during the "store the
ASO" are not. This seems to prevent the possibility of a working
cookie ASO scope.
I managed to setup a property persistence strategy that persists the
property object to a Cookie which manages to do the storing in time.
This works fine but when that object needs to be available to multiple
pages it'd be nicer to use an ASO than load the page with the
persistent property whenever it is needed.
What'd you think?

This is my log...note the empty 'object' value for CookieScopeManager
on line #7 is an empty cart whose toString() produces an empty string.
