controlling access to direct links

[Dan Adams <da...@ifactory.com>]

Okay, I have something set up that works well where if you request a
page and dont have access a PageCallback gets created and you get sent
to the login page. After loging in the callback is used to return you to
the desired page.

Now, I would like to do something similar with direct links so that if
you request a direct link and don't have access a DirectCallback gets
created, you log in, and then get sent back to the direct link. Any
ideas on how to do this?

One of the things I'm considering with this is subclassing DirectService
and overriding it. Then overriding triggerComponent() and put my
authorization stuff in there. Does this sound like a good approach?
Also, I can't seem to get the system to actually use my service.

Java:
public class AuthDirectService extends DirectService {

	public AuthDirectService() {
		super();
	}

	@Override
	protected void triggerComponent(IRequestCycle cycle, IDirect direct,
Object[] parameters) {
		super.triggerComponent(cycle, direct, parameters);
	}

	@Override
	public String getName() {
		return "cms.authdirect";
	}

	
}

hivemodule:
  <service-point id="authdirect"
interface="org.apache.tapestry.engine.IEngineService">
	<invoke-factory service-id="hivemind.BuilderFactory" model="singleton"
>
		<construct class="aspect.AuthDirectService" >
			<set-object property="responseRenderer"
value="infrastructure:responseRenderer" />
			<set-object property="request" value="infrastructure:request" />
			<set-object property="linkFactory"
value="infrastructure:linkFactory" />
		</construct>
	</invoke-factory>  
  </service-point>
  
  <contribution configuration-id="tapestry.services.FactoryServices">
    <service name="cms.authdirect" object="service:cms.authdirect"/>
  </contribution>
