I was having fun with rails right up until ajax. And now want to burn  
the  
whole thing down. Please explain what I am doing wrong here.  
index.html.erb contains:

\<%= javascript\_include\_tag 'prototype' %\> ...

I AM RJS

\<%= link\_to\_remote("hello", :update =\> "rjs", :url =\> {:action =\> "hello\_dude"}) %\>

the controller file contains:  
def hello\_dude  
render :text =\> Time. now  
end

So far everything is works. Now I try use let the rjs file :

change the controller file to  
def hello \_dude  
respond\_to do |format|  
format.js  
end

With the hello\_dude.rjs file containing:  
page.insert\_html :bottom, :rjs, Time.now.to\_s

Here is what shows up in my browser:

try { Element.insert(“RJS”, { bottom: “Wed Jul 22 23:28:17 -0700 2009”  
}); }  
catch (e) { alert(‘RJS error:\n\n’ + e.toString());  
alert(‘Element.insert("RJS", { bottom: "Wed Jul 22 23:28:17 -0700  
2009"  
});’); throw e }  
hello [http://localhost:80/orders?search=shoes#](http://localhost:80/orders?search=shoes#)

I don’t get it. Please help me get rid of this annoying error message.  
Thanks,  
Tim

sijo is right , when you use :update that try to  
update that fragment and send the response to that fragment

before the calling of rjs the response already send to that fragment
