Hi,
I'm not sure if I found a bug, or if I'm doing something wrong. Here is what happens:
We're using Rails 3.0.1 with jQuery instead of Prototype. When we create a simple ajax form (using :remote => true) and use :disable_with on the submit button, it works.
As a result of the Ajax call we use Javascript to replace the form by another partial. Because page.replace does not work with jQuery, we're doing this:
=== response.js.erb ================ $('#container_to_be_replaced').html('<%= escape_javascript render :partial => 'form' %>');
