Hi,

I have writen this SWC component. If I run a test FLA from the same folder where the AS class is, it works. But if I install the component in the components folder and try to instantiate it from somewhere else (any folder but the one where the AS class is) I get the following error:

\*ArgumentError: Error #1063: Argument count mismatch on MyComponent. Expected 0, got 4.  
\*  
Obviously, the declaration of the class component needs 4 arguments, but Flash is complaining with me.

What am I missing here?
