Tapestry IoC: Bean Scope
Hi all,
is it possible to have services bound with Bean scope? I'm using Quartz
scheduler and my jobs are actually services bound in AppModule with all
dependency injection and so on.
But i want different instances of jobs. So every time i call
ServiceResources:getService(..., Job.class)
i want new instance back.
I remember it was not possible to implement with Hivemind, how about
Tapestry-IOC?
Thanks.

Yes. JavaDoc: Autobuilds a class by finding the public constructor with
the most parameters. Services and resources will be injected into the
parameters of the constructor.

did i get you right, that i can simply inject ObjectLocator service to my
Quartz JobFactory and instantiate jobs via autobuild()
I mean sources saying all dependencies will be injected.

Unfortunately, Tapestry is not Spring :-) The proxy you get back from
a direct or indrect call to getService() is always global, though in
the case of the perthread scope, that core service implementation is
... another proxy that manages and delegates to the per-thread
instance.
I think you need to use an explicit factory if you want to control
when new instances are created. In fact, for ordinary beans, you can
get the BeanModelSource, get a BeanModel for a class, and use its
newInstance() method.
However, that's roundabout, because newInstance() gets the
ObjectLocator (which can be injected into any service) and invokes
autobuild() on it ... so it's a very generic factory.

i was hoping someone already did it :)
Last time i was trying to do it with Hivemind, proxy created a new instance
every method call, and this is not what i want. I mostly likely want
no-proxy, but just new instance.

Is what do you want the same as the prototype scope in Spring?

Tapestry-IoC provides singleton and per-thread scopes out of the box, but
you can add your own ones. Implement ServiceLifecycle2 and contribute it
to the ServiceLifecycleSource service. Take a look at the
PerThreadServiceLifecycle source for an example.
