TypeError: #1009 null object reference and a loader

Hi,

I’m having some trouble with the stage in AS3 when loading a swf into another swf.

I have a loader swf loading a swf with a document class which imports a few other classes. A sample from one of those imported classes follows:

// constructor
        function ModelInfo() {
            if (!allowInstantiation) {
                throw new Error("Error: Instantiation failed: Use ModelInfo.getInstance() instead of new.");
            } else {
                createMouseOverHeading();
                createMouseOverSubHeading();
                createMouseOverDetails();
            }
        }
        public static function getInstance(input:Stage):ModelInfo {
            if (instance == null) {
                myStage = input;
                allowInstantiation = true;
                instance = new ModelInfo();
                allowInstantiation = false;
            }
            return instance;
        }

As soon as the progress handler traces that the loader has loaded the entire swf (but before the init handler gets executed) I receive 1009 null object reference errors everywhere the stage is accessed.

Now… unfortunately, general confusion does not make for a very good question…so,

Should the “addchild” for the loaded swf be on on the loader’s onComplete handler, or somewhere else?
I’ve read about “ADDED_TO_STAGE” in several places, but how can I incorporate this into the above code?
Should the swf that is loaded compile properly on it’s own to work with the loader?
Can anyone refer a good article that explains the problem I’m having? I’ve already tried several and I’m not confident that I understand it.

Thanks in advance :slight_smile:
