I’ve got a partial that I’m trying to refresh, but I don’t get back any  
results, nor do I see any errors in Firebug. I’m guessing there’s a  
problem with the DOM, but I’m not sure. Can someone else take a look  
and let me know where I’m missing something?

Controller:

def get\_city\_list  
@show\_javascript = true  
@counties = StateList.find\_by\_state\_code(params[:state\_code])  
render :update do |page|  
page.replace\_html ‘city\_select’, :partial =\> ‘city\_list’  
end

View:

\<%= collection\_select (:state\_code, :state\_code,StateList.find(:all,  
:order =\> “state ASC”, :select =\> ‘distinct state, state\_code’),  
:state\_code, :state, {:prompt =\> ‘Select a state’}, {:id =\> :state\_code  
}) %\>

&nbsp;

\<%= observe\_field :state\_code, :url =\> {:action =\> ‘get\_city\_list’},  
:with =\> ‘state\_code’ %\>

THANKS!

Have you checked that state\_code is actually the id of the form  
element you’re interested in? I would expect it to be more like  
state\_code\_state\_code based on what you’ve got above.

Thanks for your help.

I had thought that I needed to observe :state\_code, but I actually  
needed to observe ‘state\_code’

THANKS!!!
