[flexcoders] how to call a function from a component to another

[quantum_ohm]

Hi All !

I'd like to call a function x() which is in a component X.mxml, from  a 
function y() which is in another component Y.mxml...

(As my components are called several times in different states I can't assign 
them any id : so this.parentApplication doesn't fit)

How to do this ?

Thx for help.
