Maybe SA should check if component does not already have a function with same name before creating it. Then it would be possible to factorize code and do not need to create Controller or create a function redirection.
It would be nice if it was possible to have a combo listing all available functions of 'me'
EDIT : please note that SA detects if I want to add a Basic Function named 'onSearch' : 'This handler name 'fn' is already in use or reserved. Please enter a unique name'
