form_remote_tag running only once

I'm trying to add a simple search to an index page of my project. It takes a term, does a 'like' query and populates a common partial which is displayed with javascript in the div 'search_remote'.

It runs fine, once. If you run multiple queries without hiding the div, it works fine. If you close the div and attempt to search again you get nothing. The console shows that the controller method is firing but the div isn't getting updated.

In the view:   <% form_remote_tag :update=> "search_remote",:url => { :action => "search_remote" } do %>     <%= 'Search for Description:' %>     <%= text_field "description", "description" %>     <%= submit_tag 'find' %>   <% end %>   <div id="search_remote">   </div>

In the controller:   def search_remote     if params[:description]       search_term = params[:description][:description]       search_term = '%' + search_term + '%'       @search_results = Item.find(:all, :conditions => ["description LIKE ?", search_term])       render :partial => "search_remote", :locals => {:aGroup => @search_results, :show_hide => 1, :aToken=> 'search_remote'}

In the partial _search_remote:

<%= link_to_remote 'hide',   :update => 'search_remote',   :url => {:action => "search_remote", :token => 'search_remote' },   :complete => visual_effect( :blind_up, 'search_remote', :duration => 0.2 ) %>

Thanks

Doesn't look like you ever show the div after hiding it.

Thanks Fred.

You pointed me in the right direction.

The problem seemed to be in the form_remote_tag element. I changed "text_field" to "text_field_tag" which got rid of the double params for description.

I also changed the div name by adding "_div" to it on the possibility that having the same method and div name might have caused the confusion.

Then adding a "render :nothing => true" to the search_remote method cleaned out the div.

In the future, I think I'll add a separate search page.
