i am not 100% certain i understand what you mean (heads a bit thick with anti-flu medicine) but here is a nice rule of thumb.once a class is instantiated the "this" property is always the same no matter where you call it from (google method closures)

I didn't entirely understand your answer, but now that I tried this, it works, and your answer made more sense:

var pendingCall = myService.someMehtod(arg:Type, arg2:Type);pendingCall.resultHandler = resultMethod;

The RemoteObject, myService is being created in the main app, this code is being used in a component. So I see that the scope issues are taken care of automatically, which is nice. The reason I am doing this is because my services will be passed into each component by the main app, so if different components need to call the same methods, I need local result handlers.

  delegates are build into as3, so if you assign an event handler it will execute in the right scope. i cannot help you with WS implementation in AS3 yet.

I'm trying to add resultHandlers to async method calls at methodinvocation time (this approach is outlined in the 'Developing Rich Clients with Flex' book). I have also done a very similar approachwith Flash and Remoting. So code that used to work is like this:
var pendingCall = myService.someMehtod(arg:Type, arg2:Type);pendingCall.resultHandler = mx.utils.Delegate.create(this,resultMethod);with result method being some local method. Anyway, now I can't

locate the mx.utils.Delegate class for one thing. I did, throughviewing errors, find that the pendingCall object with be of type 'mx.rpc.AsyncToken', I tried to addEventListener, but I still got anerror that resultHandler was not set on the pendingCall. Anyone have
any good ideas here? How do I properly attach a resultHandler to anAsyncToken in Flex 2 Beta 2? Thanks for the help!Chris Scott
