page.visual_effect

I have something similar to a blog post that users can add comments to.
I'm use a partial to render the list of comments and a form that submits
a new comment via AJAX to update the list. The AJAX call uses the same
partial. My question is, how can I mark the last added comment so that I
can use page.visual_effect to give it a yellow fade. Currently, I can
highlight the entire block of comments. Everything I've tried causes
problems. :after_create won't work, as far as I can tell, because it's
wrapped into the create method and no changes have been committed to the
database yet.

This seems like it should be a pretty simple task, highlighting the last
change to a list rendered as from a collection, but I can't figure it
out. Any thoughts?

maybe I'm being completely dumb, but can't you do

render :update do
  page.insert_html :bottom, 'comment_list', :partial =>
'comment', :object => new_comment
  page.visual_effect dom_id(new_comment)
end

or something along those lines ?

I tried something similar (though I'm placing the comments at the top)
and it worked -- unless you submit more than one comment without
manually reloading the page. Then it didn't update / highlight
correctly.

Here's what I tried (I call them notes):

page.insert_html :top, 'query_notes', :partial => 'queries/notes',
:collection => @note
page.visual_effect :highlight

Aren't you some missing method arguments there ? I'd check that
you're not stuffing invalid HTML into the dom (or duplicate ids or
anything like that)
