\<%= text\_field\_tag :user\_search, params[:user\_search] %\>

```
     <%= apply_behaviour "#user_search",
       make_observed( :field,
         :update => 'contresults',
         :with => "'user_search=' + escape($F('user_search'))",
         :url => { :controller => 'community', :action =>

```

‘search’ } ) %\>

```
     <div id="contresults">
     </div>

```

this should call this code

def search  
puts params[‘user\_search’]  
end

Of course I’ve included UJS, changed application.rb with various  
session\_id stuff, included everything needed (it generates js files  
correctly, the problem is that it’s empty …)

Someone has an idea of what’s happening here ?
