I use an enhanced version of the CookieSource implementation. I just
create it as a service using my implementation and use that in my pages,
components and services. You can do that until the framework provides
what you want. I put it in my hivemodule like this:
<service-point id="CookieSource"
interface="com.elidoran.tapestry.CookieSource">
<invoke-factory>
<construct class="com.elidoran.tapestry.DefaultCookieSource">
<set-service property="request"
service-id="tapestry.globals.HttpServletRequest"/>
<set-service property="response"
service-id="tapestry.globals.HttpServletResponse"/>
</construct>
</invoke-factory>
</service-point>
To see the source changes I made you can check out the patch I provided
for the standard classes here:
http://issues.apache.org/jira/browse/TAPESTRY-419.
I've been using the enhancement through many of the beta versions and
had no problems. I use it in a persistence strategy that persists
properties to cookies. The framework compiles and runs fine with the
changes.

Using Annotations, this has worked for me:
@InjectObject("service:tapestry.request.CookieSource")
public abstract CookieSource getCookieSource();
and then:
getCookieSource().readCookieValue(name);
or
getCookieSource().writeCookieValue(name, value);
One limitation is that writeCookieValue does not yet handle expiration
dates (according to the TODO: in CookieSource.java).
The second part of your question would involve hooking into one of the
HiveMind engine services involved in handling each request (possibly
Tapestry.request.WebRequestServicer). In Tapestry 3, it was a simple
matter of overriding BaseEngine and implementing setupForRequest().

Hi,
I'm trying to create a persistent cookie to be placed in the user's
browser
but I just can't figure out how to do it in Tapestry 4. I've looked
around
in the list archives and in the docs but I couldn't find anything
that would
help me (except for the CookieSource class which didn't seem very
helpful in
my case). Anyone know how this can be done?
Another thing is that for every request I must read this cookie and
update
my database with some info (regardless of which page the user is
accessing)
and on every response I might have to change the cookie's contents.
How
would I go about having a class/method that is called on every
request/response so that I can read/update this information? I'm
thinking
it's some hivemind thing but I guess I'm just not fluent enough with
it yet.
Can somebody help me?
Thanks,
Denis Souza
