Hi Anthony,
I have to say, your proposal is logically correct. Good hint!
Furthermore, I find a more appropriate place to add those code. That
place is generic.load.
However, my complicated action "index" contains multi components, some
are even duplicated. Then after I deploy the new generic.load, the
"index" page's appearance or behavior is not 100% correct. I guess
that is caused by duplicated and/or improper location of those
component css&js files.
Experiment abort. :-(
Regards,
Iceberg
