Oh, well, Paul.
Your help did produce many things interesting to me: now I have some more
classes in my tree, among which a nice RequestLocaleManagerImpl. Also, I
brought the <implementation> hint into my hivemodule.xml.
But... How I'm expected to inject a specific Tapestry ASO to my implementation
of the RequestLocaleManager?
I really tried hard a lot, getting even more confused. ASOs are a Tapestry
enhancement to Hivemind and it seems to me that Tapestry also defines a schema
and a configuration point for them: the BuilderFactory details you suggested
are a bit too wide in scope.
How should I access them?
My hivemodule.xml actually carries something like the following:
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="locale" scope="session">
<create-instance class="LocaleASO"/>
</state-object>
</contribution>
...
<implementation service-id="tapestry.request.RequestLocaleManager">
<invoke-factory model="pooled">
<construct class="RequestLocaleManagerImpl">
<set-service property="request"
service-id="tapestry.globals.WebRequest"
>The WebRequest object</set-service>
<set-service property="threadLocale"
service-id="hivemind.ThreadLocale"
>The ThreadLocale object</set-service>
<set-service property="threadLanguages"
service-id="ThreadLanguages"
>The ThreadLanguages object</set-service>
<set-service property="hibernateSession"
service-id="confesercenti.hibernateSession"
>Our reference to the Hibernate Session
object</set-service>
<set-object property="applicationObjects"
value="configuration:tapestry.state.ApplicationObjects"
/>
</construct>
</invoke-factory>
</implementation>
Don't mind the threadLanguages and hibernateSession objects: they are services
of my own. The problem is the applicationObject one: how I am expected to get
an instance of the ASOs (or even to inspect if it had been already stored into
the session)? Do I have any simpler method to inject my own "locale" ASO into
the object, of course respecting the session boundaries?
I've got the feeling that Hivemind is not that well documented and that the
Tapestry-contributed hivemind modules aren't at all...
Thanks again,
