Hi,

I´m using the Lightning-Fast Javascript Autocompletion recipe from  
Rails Recipes.

When I add or remove users in the contact list, changes are  
immediately reflected in the conacts\_for\_lookup js array. Indicating  
that both the javascript and method is executed when reloading  
\_send.rhtml  
But after a while, the js array is empty:  
var contacts = new Array(0);  
Is there a caching issue, causing the method not to be executed every  
time?  
If I logout and in again, the array is back.

I´m running in development environment.

views/sms/\_send.rhtml

contacts\_controller.rb:  
def contacts\_for\_lookup  
@contacts = Contact.find(:all,  
:conditions =\> “company =  
‘#{session[:user\_number]}’”)  
headers[‘content-type’] = ‘text/javascript’  
render :layout =\> false  
end

contacts\_for\_lookup.js  
var contacts = new Array(\<%= @contacts.size %\>);

\<% @contacts.each\_with\_index do |contact, index| %\>  
contacts[\<%= index %\>] = “\<%= contact.name %\>”;  
\<% end %\>

Any tips or hints are highly appreciated! 🙂

Regards,
