It is. It hangs "magically" off of the ActivationObject, and no one has a
clue how nice that is with the Garbage Collector. Instead, use a Delegate.
import mx.utils.Delegate;
function connect()
{
mySocket = new XMLSocket();
mySocket.onXML = Delegate.create(this, handleIncoming);
}
function handleIncoming(xmlStr)
{
// this is scoped correctly to the class
trace(this);
parseMessages(xmlStr);
}
>>function connect ()
>>
>>{
>>
>> mySocket = new XMLSocket ();
>> var _obj = this;
>>
>> mySocket.onXML = function ()
>> {
>> _obj.handleIncoming();
>> }
>>}

Nothing is "wrong" with it. Just seems an ugly way to deal with
differences in scope.
