Problem with Ajax response with the use of action.js.rjs file

Rails
1

I am trying to get a grasp of Ajax response in ROR. Following the
examples in the ROR API and the books Simply Rails 2 from Sitepoint,
following are the code snippets from votes_controller and
create.js.rjs:

(from app/controllers/votes_controller.rb)
def create
@story = Story.find(params[:story_id])
@story.votes.create(:user => @current_user)

respond_to do |format|
format.html { redirect_to @story }
format.js
end
end

(from app/views/votes/create.js.rjs)
page.replace_html ‘vote_score’, “Score: #{@story.reload.votes.size}”
page[:vote_score].visual_effect :highlight

Following is the code from (app/views/stories/show.html.erb) that
triggers the create action in the votes controller:

<% form_remote_for [ @story, Vote.new ] do |f| %> <%= f.submit 'shove it' %> <% end %>

When I hit the above shove it button, I am getting the following error
(from the firebug console window)

NameError in Votes#create

Showing votes/create.js.rjs where line #1 raised: 

undefined local variable or method `page' for
#<ActionView::Base:0x46caf94>

Instead when I change the create def to include the inline JavaScript
statements as follows, its working:

def create
@story = Story.find(params[:story_id])
@story.votes.create(:user => @current_user)

respond_to do |format|
format.html {redirect_to @story}
format.js {
render :update do |page|
page.replace_html ‘vote_score’, “Score:
#{@story.reload.votes.size}”
page[:vote_score].visual_effect :highlight
}
end
end

Looks like the JavascriptGenerator is generating the necessary
JavaScript if the statements are inline instead of in a separate view
file. Is is behavior expected.

PS: I am working on WinXP using InstantRails with Rails 2.1

Thanks in advance.
