Hi,

I found out there is a new parameter for the "render" function, but I couldn't find any information or documentation on it, specically on what we can do with |page|, there are examples on the new book "agile Web Development with rails", but it doesn't contains any information about it, like: on p.559

... render :update do |page|

This was confusing for me too at first. It's an instance of the JavaScriptGenerator class: http://api.rubyonrails.com/classes/ActionView/Helpers/PrototypeHelper/JavaScriptGenerator/GeneratorMethods.html

And if you're going to use the page.visual_effect method, more info about that is here: http://api.rubyonrails.com/classes/ActionView/Helpers/ScriptaculousHelper.html

I think |page| is often used instead of |generator| to help you think about what you're doing to the web page, and worry less that you just happen to be doing that indirectly by generating javascript.
