Hi Carlos, as Harbs mentioned, my experience is also, that implemented interface methods or overridden methods always has to be implemented with the entire same signature, including optional (default parameters) and required parameters.
>From the AS3 docs regarding interfaces [1]: "You also have some flexibility with default parameter values. An interface definition can include function declarations with default parameter values. A method that implements such a function declaration must have a default parameter value that is a member of the same data type as the value specified in the interface definition, but the actual value does not have to match" Why do you think that this doesn't make sense?
