Re: problems getting a session state object on start up (resend ..? )
o.k. so it doesn't have to work... It doesn't look like there is any way to get to the Hivemind Registry until it has completely initialized ... which is too late. So I am going to have my stateObjectFactory check to see if it can get to the registry which is a little bit hacky and if it can't then create a session object that it tracks itself rather than using the applicationStateManager. There should be a better way! On 9/26/06, Patrick Moore <[EMAIL PROTECTED]> wrote: I have given myself 1 more hour before I use my fallback solution.

I remember spending an afternoon with a coworker once trying to do the
same thing, feed a fake request/session to Tapestry for some similar
reason. After a few hours we decided it was a silly idea and gave up on

Hi Ben --
What I am trying to do is preload some sample data, *as if* a user has
entered it. So I want to have a Session object that I am going to
programatically configure. Also I will be doing some background

on behalf of a user so I will need to have a session object for that
case as
well. In neither case do I have a HttpRequest

I'm not sure what you're trying to do makes sense, if I understand this
correctly. It sounds like you are trying to directly access a

The problem is you aren't going to have a web session without an
associated request from the user, which isn't going to be there at the
point the Hivemind registry is created.
In my case, I needed to eager-load a service that needed the asoManager,
but I didn't actually pull any ASOs out of it until later while
processing user requests.
If you're trying to setup some initial state in each ASO as it is
created, couldn't you add an initialize() method to the ASO class and
create it using ?

I hope that works for you, unfortunately I'm out of ideas on this one.
I'm not sure what you're trying to do makes sense, if I understand this
correctly. It sounds like you are trying to directly access a
session-scoped ASO as your eager-loaded service gets created, correct?
The problem is you aren't going to have a web session without an
associated request from the user, which isn't going to be there at the
point the Hivemind registry is created.
In my case, I needed to eager-load a service that needed the asoManager,
but I didn't actually pull any ASOs out of it until later while

created, couldn't you add an initialize() method to the ASO class and
create it using ?

RE: problems getting a session state object on start up (resend ..? )
Hi Pat,
We ran into a similar situation and found a workable (but not pretty) solution.
First, you need to contribute to the ApplicationInitializers contribution point
as described in this thread:
http://article.gmane.org/gmane.comp.java.tapestry.user/33013
But in this case you'll want to make sure your service is created after the
ApplicationStateManager has been setup, so it should look something like this
in hivemodule.xml:
Then set the service you want to eager-load on "MyInitializer" and call
something on it inside the initialize() method to ensure it gets created:
public void initialize(HttpServlet servlet)
{
myEagerLoadedService.initializeMe();
}
Maybe someone else knows a better way, but this is the best I'm come up with to
deal with the issue of eager loading services that need the infrastructure.
Ben
