Rails - Apr 2006 - Validation error messages help please

I''m having problems with validation error messages appearing in my app.

In Controller:
def permissions
    @roles = Role.find(:all, :order => ''name'')
  end

  def new_role

    @role = Role.create(params[:role])

    if request.post? and @role.save

      flash[''notice''] = ''Successfully created a new
Role''
      redirect_to :action => "permissions"
    else
      flash[''notice''] = ''The Role was not created.
There was an error
try again''
      render :action => ''permissions''
    end
  end

Basically I have a permissions page that has a form on it to create new 
roles. If the role is created correctly it redirects to the permissions 
page and displays the flash. When it fails the display is fine but the 
URL now shows "accounts/new_role". But I am clearly rendering 
permissions not new_role. If I change it to "redirect_to" then it 
display the "accounts/permissions" page fine but my validation errors
do
not display? Anyone shed some light onto what is the correct way please?

That is how it''s supposed to work. :P

The thing is, when you click the submit button you are redirected to the 
"new_role" action; when validation fails you''re still in the
new_role
action. Then render :action doesn''t change the page: it just renders
the
selected action within your current page, and that''s why it displays 
your validation errors properly.

I don''t think this can cause any problems, nor do I know of any ways 
around it.
