Hi

I just wanted to note an issue that has been around for some time and
it is related. Sometimes you have a bunch of .js or .css files and you
want to group all of them into a single file. To do that, you can
create a custom ResourceHandler and redirect the resource requests to
the suggested resource that joins all the files or use some library
that has already that logic.

It would be great if JSF by default could handle that "alias" logic.
If the project stage is Development then load the uncompressed files,
but if it is Production use this compressed javascript. That would
improve performance and has been mentioned in the past. Some people
has already provided solutions.

Please note this logic can be made to override jsf.js javascript as
well. But from design perspective I don't feel very good about have
alternate versions of jsf.js, instead I would like to make jsf.js work
even with portlets.

It is a fact that JSF is very pluggable from the java perspective, but
the fact that you cannot customize the behavior of jsf.js (pass config
params on initialization like project stage and others) becomes a
problem.

regards,

Leonardo Uribe
