I needed something similar. but listing those in a TR tags in a table. had to modify the blueprint and the way it is handled

Maybe having a selector option that jQuery would use will help. You may have something like:

link_to_add "Add Task", :tasks, :selector => "tr .task .fields"

I ported cheba's basic change over to the latest code. I couldn't easily port the code that supported wrapper procs, and I didn't need it, so I let it go.

@modsaid storing the blueprint in textarea is not a good idea, if you have a textarea in your form the <textarea> tag will respond with the </textarea> from the form, and give some strange results.
I also want to store table rows, and I'm facing this issue.
my first thought was to store the blueprint in a javascript variable... but I'm torn

For the record, I escaped the HTML with a rails helper, and then I sent it to javascript variable.

Server side :

  @template.after_nested_form(association) do
    model_object = object.class.reflect_on_association(association).klass.new
    "<script>window['#{association}_fields_blueprint']=\"#{@template.escape_javascript(fields_for(association, model_object, :child_index => "new_#{association}", &@fields[association]))}\";</script>"
  end

And then browser side :

  var content = window[assoc+'_fields_blueprint']; // Fields template

Works great !

Thanks for the note @elmatou, this will be more generic of course..

The original issue was fixed in e866f4f. I'm going to write a "How to" about using nested_form with tables. Thanks everyone!
