in Rails 2.1, this works… but I am stuck w Rails 2.2

class PostsController \< ApplicationController  
def show  
…  
respond\_to do |format|  
format.html  
format.atom { render :action =\> ‘changes’, :layout =\>  
false, :content\_type =\> ‘application/atom+xml’ }  
end  
end

def changes  
…  
respond\_to do |format|  
format.xml { render :layout =\> false, :content\_type =\>  
‘application/atom+xml’ }  
end  
end  
…  
end

I have a view, changes.xml.builder, building the xml code, but I got  
a missing template as an error, when executing  
[http://localhost:3000/posts/show/5](http://localhost:3000/posts/show/5)

ActionView::MissingTemplate (Missing template posts/changes.erb in  
view path …/Projects/franchising/app/views:):  
If I set a changes.erb, the xml code is sent…

how should I write that w Rails 2.2 ?

thanks a lot for your help
