I've got a problem with ServiceLocator, and that problem didn't
exist until my today's Flex & Cairngorm upgrade (to Hotfix 2 +
Cairngorm 2.2).

Context:
--------
In my <mx:ServiceLocator> I've got 3 web services defined, one of
which is a public one (the others are protected). "Public" means
it's not secured on the server and contains only "login(user, pass)"
method (and it has a known URL in the application start). After the
successfull login, the login method returns WSDL URLs of all other
web services.

Problem:
--------
The problem is that a service locator IMMEDIATE LOADS ALL WSDL-s of
it's (web service) children. But: this happens only when the
ServiceLocator is referenced FROM THE DELEGATE CLASS (using 'service
= ServiceLocator.getInstance().getWebService("publicWebService") as
WebService;'). When it is referenced from the main page, this
problem doesn't exist. Of course, these other web services doesn't
have proper WSDL-s assigned yet, so I got an error.

Note: I HAVE TO reference the web service from the delegates since I
have to invoke web service methods from that delegates.

Since I didn't quite understand what's going on here, please give me
some advice. Thanks!

Code:
-----

public class LoginDelegate
{
private var responder: IResponder;
private var service: WebService;

public function LoginDelegate(responder: IResponder)
{
service = ServiceLocator.getInstance
().getWebService"publicWebService") as WebService; // this is the
line which brings up error
this.responder = responder;
}

public function login(user:String, pass:String):void
{
var token:AsyncToken = service.Login(user, pass);
token.resultHandler = this.onResult;
token.faultHandler = this.onFault;
}

//-----------------------
protected function onResult(event:ResultEvent):void
{
responder.result(event);
}
protected function onFault(event:FaultEvent):void
{
responder.fault(event);
}
}

Error Detail:
-------------
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
