Hi!  
I’m on Rails 2.2.2 and using text\_field\_with\_auto\_complete which works  
fine.

Now I want to use :after\_update\_element to send some data back to the  
server when my text field is updated.

I have the following code in my view:

\<%= text\_field\_with\_auto\_complete :company, :name, {},  
{:after\_update\_element =\>  
“function(element,value){” + remote\_function(  
:url =\> { :action =\> :update\_search\_session },  
:with =\>"‘selected\_company\_name=’+element.value") + “}”,  
:skip\_style =\> false, :method =\> :get }  
%\>

I can see that my controller method (:update\_search\_session) gets called  
allright but I can’t figure out how to access the returned data  
(element.value).

Can anyone help?

TIA, Peter

OK finally I got it sorted out.  
After a minor bugfix in my javascript, params[:selected\_company\_name]  
did the trick.

Amazing and smooth… - I just love Rails!
