Re: Rails3: jquery-rails gem sets ''config.action_view.javascript_expansions'' but cannot be overriden in ''config/application.rb''

True but I was wondering why it didn''t work.

In the jquery-rails (which is actually a railtie) there is the code:

config.before_initialize do ...
     <set expansions>
end

So this could mean that during initialisation (in your
config/application.rb) you could easily change this yourself but as it is
now, it doesn''t work.

So I was wondering whether this is expected behavior or not.
