Rails - Feb 2006 - validation error reporting on child object

How does one deal with validation error messages on child objects of the main
model object
behind a page?

I have the basic blog w/ comments page (only my "entry" is a
"proposal"). I have the
comments saving just fine, but I wanted to show an error if the user hits the
submit
button without typing anything in the comment.

I added "validates_presence_of :comment_text" in my Comment AR class,
and it appears that
the empty comment is no longer being inserted into the db. However, I
can''t figure out how
to display the error message on the comment object (1 to M child of proposal) in
the page.

I put an else on the call to save the comment in my add_comment action and that
works. But
I can''t figure out where the error message going. Looked at
"@proposal.comments.inspect"
in the view, I don''t see an error message.

thanks,

b
