render :update returns js wrapped in a HTML body

Hi.

From what I'm learned the below is suppose to return "alert('Im JS');"
to the javascriptGenerator that's suppose to make the page scream 'Im
JS'...(?)

render :update do |page|
  page.call :alert, "Im JS"
end

In Rails 1.2.3 it works perfectly.

BUT in Rails 2.0.2 it returns the js neatly wrapped in a full HTML-body,
and the browser shows me nada... (!)

Please help me here, I've tried everything I can think of for hours now!

Random things I've tryed (not in any order, and just glimpses)
1. use the page/hi.js.rjs
2. use the render :text => "alert('Im JS');", :content_type =>
"text/javascript"
3. respond_to do |format|
     format.js
   end
4. headers["Content-Type"] = "text/javascript; charset=utf-8

Thank you all in advance!

Is rails being dumb and adding a layout ? (in which case
adding :layout => false should help)

Is rails being dumb and adding a layout ? (in which case
adding :layout => false should help)

My guess once too, but 1. it's not my layout that's being rendered
around the JS, but just a <html><head><title></title></head><body>my
code</body></html> and 2 I've tried:

render :update, :layout => false, :content_type => "text/javascript" do

page>

  page.call :alert, "Im JS"
end

(sorry for not mentioned that above!)

Thanks for your help, please let me know if you can think of anything
else...

Hi.

I found it!

Argh, why didn't I check this earlyer:

The bad guy:

Code :
   1. #application.rb
   2. after_filter :tidy
   3. def tidy
   4. RailsTidy.filter(response)
   5. end

Thanks all for reading my post. Hope this helps any one else in the
furure.
