external use of hivemind services
Hi,
i have my Hibernate SessionFactory installed as an application wide tapestry.state.ApplicationObjects.
How can other Objects that can not use the @Inject Annotations access this service?
The Objects are in the application, but they are not direct in a page or component.
Like a User Manager that is called in Page. I dont want to refer to the service i injected by a parameter.
thanx

Turn them into hivemind services. This way, when constructing the
services, use auto-wiring or use <set-service> inside <construct>.
Then inject them into your pages or components.

The trick is to get the ApplicationStateManager object, and obtain the
state object from it.
If you have an IRequestCycle, you can invoke
getInfrastructure().getApplicationStateManager()
You can then invoke get() on the ASM, passing the name of the state object.
The @InjectState annotation is, effectively, building this code for you.
If you are building a HiveMind service, you can inject the ASM using:
<set-object name="manager" object="infrastructure:applicationStateManager"/>
