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)
