Hi,

I just started learning django last week and my flash cs4 is a bit dodgy as well. I'm trying to create a writing support tool for 7-11 year olds. Basically the kids type things and every time the space bar is pressed I'd like to send django what they have written so far -parse it in different ways and then send some supports back up to flash.

I've taken the Hellow World example from the pyAMF docs and tried to modify it. When I load the swf file into my browser from my static webspace it gives me no error message or return statement what-so-ever. If I just

I would check crossdomain settings here.

run 'test movie' from my desktop the HelloWorld package returns the following message:

 -----------------------------------------------------------------------Returned Message-----------------------------------------------------
Remoting error:
Service.ResourceNotFound

Unknown service echo.echo
error
['Traceback (most recent call last):', '  File "build/bdist.linux-i686/egg/pyamf/remoting/amf0.py", line 75, in __call__    request.target)', '  File "build/bdist.linux-i686/egg/pyamf/remoting/gateway/__init__.py", line 367, in getServiceRequest', 'UnknownServiceError: Unknown service echo.echo']

----------------------------------------------------------------------------------------------------------------------------------------------------------

On the AS3 side it oddly calls the HelloWorld function before the spacebar is ever pressed (but I'm guessing that that problem is unrelated to the error above).

I'd just like to know what I have out of place or what I need to add.  :-)

thanks,

Justin





I'm not sure I needed to include all these files but, being new I thought I would err on the side of inclusion.
