Render RJS and action from submit_tag ?

I'm using "file column" for multiple image uploads. Sometimes it takes
a while for the upload to complete and I would like to provide a tiny
bit of feedback to the user while it's uploading.

Right now I don't need a progress bar. I'm using mongrel so don't even
know it that's possible yet. Instead, I created a simple RJS template
(my first- woo) that says "File uploading, please wait..." with an
animated gif. Created a simple link_to_remote , tested it out, works
great.

Now, when submitting the form, I can't figure out how to call both the
RJS template and the action in my controller. Tried render :action =>
'uploadindicator' in the action itself but get the "Can't have multiple
renders" which makes sense.

Played around with 'submit_remote_tag', with no luck. :loading looks
like it only works with link_to_remote or form_remote_tag.

Any help would be appreciated.

Thanks for the info. I think I'm getting closer.

However, I really do want to render two things. When the files are
uploading (beginning of method), I want to display a message
(Uploading...) and when the files complete (method completes) I want to
display another message (Images successfully uploaded.).

I can't call the rjs directly because I'm uploading files with
":multipart => true" and ajax can't handle files/images.

Played around with a hidden iframe, but can't get around having to
render twice.

So I'm still stumped.

BTW, I had a misprint in my original post. I said that I've tried the
"render :action =>" and meant to say "render :update =>".

Have a look at the plugin here: http://sean.treadway.info/svn/plugins/responds_to_parent/README
It lets your use respond_to_parent and an rjs block to get your rjs to eval in the parent window. This uses the hidden iframe solution and it works well from what i've heard.
