Oh, I wasn't talking about sticking it in a class. That'd be... ugh. No.
I meant to have some class, presumably a singleton, hold the Registry.
But certainly not a domain object. Never. Ever.

It's better to have a simple singleton factory to contain the registry.
Plus if you were crazy enough to put it into a domain object as a reference
(or any service reference) you need to make sure it's marked as transient so
it will be ignored when serialization occurs for the domain object.

Well, having a Registry instance in some class is what you would do if
you were to run Tapestry 5 IoC as part of a non-web application.
I guess you could subclass TapestryFilter and override the init method
to get a hold of the Registry for retrieval through a static getter,
although I'm not sure how clean that is and what, if any, the
ramifications would be.

First, I don't think it's good practice to inject services into domain
objects. If some operation of domain object really needs to use a
service,
you could pass a service instance to that specific method instead of
injecting it.
To my understanding, Tapestry dependency injection is mainly for
services.
You could inject a dependency as a parameter of the service builder
method,
or as a parameter of the service implementation's constructor(for
autobuilt
services), or as a parameter of the module builder's constructor.
when using (build-time) AOP i need a reference to the registry, but how
do
i get it?
The default Tapestry application registry is created in TapestryFilter,
and
I don't see it's published out.
You could of course create your own registry using RegistryBuilder and
publish it somehow, but I don't think that's a good practice to have a
registry in your class and retrieve services from it.

hi all,
is it possible to use tapestry-ioc to inject services into domain

to the fields.
i'd appreciate any suggestions!

example code:
public class Order {
@Inject Repository repository;
@Inject Notification notification;
