Render, partial, and cancel button issues....

I am using a form_remote_tag to create a new object in my web page.

When the save is successful, then it displays the list and added current object in a partial.

I have two questions:

1. When the save fails, i want it to just revert back to the original list, and close the form that allows users to add new objects.

2. I would like my Cancel button on creating this new object to work, presently I can close the form, but then I get a MIssing Template message in the screen, or with some hacking, the objects list duplicates itself in the render.

:- so on this 2nd point, I want to know how to escapoe the render and revert back to the main list, on when first entering the page. I have tried :render and :redirect_to but this just duplicates the list again in the same page.

MY CONTROLLER:   # create a new product   def create     @products = Product.find(:all)     @product = Product.new(params[:product])       if @product.save           render :partial => 'product'       else           redirect_to :action => 'list', :id => @product       end   end

MY VIEW: <h3>Products</h3> <div id ="test">   <ul id="product_list">     <% @products.each do |p| %>       <li><%= link_to p.title, :action => 'show_versions', :id => p.id %>       <%= "(#{p.versions.count})" -%></li>   <b><%= link_to 'Edit', {:action => 'edit', :id => p.id} %></b>   <b> <%= link_to "Delete", {:action => 'delete', :id => p.id},         :confirm => "Are you sure you want to delete this product?" %></b> <% end %>

</ul> </div>

<p id='add_link'><%= link_to_function("Add a new Product", 'Element.show(add_product)')%></p>

<div id='add_product' style="display:none;">   <%= form_remote_tag(:url => {:action => 'create'},         :update => "product_list", :position => :bottom,          :html => {:id => 'product_list'})%>       <p>Name: <%= text_field "product", "title" %> </p>       <p>Description: <%= text_area "product", "description", :size => "30x10" %></p>     <%= submit_tag 'Add', :onclick=> 'Element.hide(add_product)' %>     <%= button_to 'Cancel', :onclick=> 'Element.hide(add_product)' %> </div>

Even some suggestions would be great, because googling this issue, doesnt really churn up much.
