Rails - Mar 2005 - Displaying error_messages_for when view is in one controller and processing in another

I have thought of work arounds but I wonder what the prefered way of doing the
following is.

I have a view in my post controller that displays an entry for my weblog as well
as a form to add a new comment.  Whe you submit a new comment it is processed in
the comment controller.  If an error occurs I need to take the user back to the
view that is in the post controller though and to do that I can''t  use
a
render_action but a redirect_to where I loose all my error messages.  How would
I go about doing this.

I have thought of doing the comment processing in the post controller, I have
also though about doing the validation in the post controller and then
processing in comment controller.  What do you guys suggest?

Thanks Again.

One way that might satisfy the elegence factor is to treat your
comment controller as a component in this case, calling
render_component within your post controller where you need to process
the comment.

There are a few ways you could do this with the component feature of
Rails 0.10 without resorting to orphaning actions within controllers
where it just doesn''t feel like they belong.
