RTE using FilePublisher in Flash CS 5.5

Question

Hello world. I'm having extraordinary difficulty using the FilePublisher class from the Flash CS 5.5 environment. I think I've tracked down the problem, but have no idea how to fix it.
I'm trying to make a prototype application that essentially functions as a dynamic online powerpoint presentation. To this end I've thusfar created an application (largely from the samples) that allows users to connect to a room hosted through LCCS, see who all is there and supports basic chat.
The problem originates from the next step, where I try to upload images to the service.  In a nutshell, if I try to use any of the methods like browse() or  uploadFileReference(), I get null refs (Error #1009: Cannot access a property or method of a null object reference) despite the fact that I'm instantiating a new publisher on the line immediately prior before trying (publisher==null is false as well at this point).
I've read this post (http://forums.adobe.com/message/1054513) and suspect that the fact that I can't call initialize means the publisher isn't getting added to the display properly. However, I can't use initialize as it is done with the Flex example because the swf won't compile (Error 1061: call to a possibly undefined method "initialize") when I try to call publisher.initialize(), even though the editor can see all of the other methods outlined in the documentation.
Trying to manually add the publisher to the display with AddChild(publisher as DisplayObject) fails, because while publisher traces out to being not null, publisher as DisplayObject DOES trace out as null. So the 64 thousand dollar question is;
How do you get the darn FilePublisher to work with CS 5.5 when you can't initialize() it? Or, how do you cast it so you can?
Also, I'm using 10.1 player, AS3, and the swc compiled as FlashOnly.

Hi,
For the flash only swc, you dont need the initialize functionality. As
mentioned in the post, intialize() function is called when the
FilePublisher component is added to a Flex container. In the flash only
swc we have decoupled it from Flex and its mechanisms, and it required
us to eliminate intialize functionality. So, calling
filePublisher.subscribe() should instantiate all the needed variables.
In summary, the thread you mentioned is Flex specific, and doesn't apply
to the scenario you mentioned. Subscribing to the filePublisher manually
might fix your issue.
If you are still stuck, Can you post your code and debug logs if possible,
Thanks
