Thank you Anthony for your comments and here comes my clarification.
You are right that, adding response.files within a component, has no
effect at all when called by "component.load". But I still keep a copy
of those response.files inside the component, because they are needed
when visiting "component.html" (during developing or debugging phase).
On the other hand, when we have to copy those response.files in action
"skeleton" or action "index", that does not feel elegant, because
action "index" has to explicitly include some helper resources which
not needed by itself. Imagine that, after I change implementation of
"component" later, I have to modify "index" also. Grrr.
Pbreit's suggestion is what I can do right now (thank you Pbreit too),
it is DRY, but still not solving the unnecessary coupling mentioned
above.
Regards,
Iceberg
