Hi Matt, What I need is to callback a function at the object that instantiated my class.
My class wraps the flex webservice object, it calls the webservice operations e drives the result event so that the operation can be executed synchronously. The class needs a reference of a function to be called back before it calls the webservice operation. In .NET we have a delegation process implemented so that we define a delegate that will be driven by anyone who needs to receive the event. In Flex 2.0, I presume, that this can be implemented by the listeners, like in java. Is it the right feature to be used or there is simething more adequate ????
