Rails - Jul 2006 - Clearing out AR object''s errors array on multiple form posts

I have a form that is POSTing to modify an ActiveRecord object @obj.

I''m using @obj.errors.add() to add to the set of errors for this form.

When I post with incorrect data, I see the error message.  However,  if 
I post again, without changing anything, the error is being added to the 
array.

Should I be calling @obj.errors.clear at the beginning of my controller 
action to
ensure that I don''t keep appending to the array?

Thanks,
Wes
