There's no additional trace information in the log, just the warning.
Is there an option to turn on full backtraces for warnings? That
would certainly help identify the source of the problem.
The code snippet I provided was from lib/haml/helpers/
action_view_mods.rb in the plugin, around line 50.
You are correct that this is a form call, specifically form_remote_tag
(I took out the '_remote' and it still have the same warning). Here's
my code:
- form_remote_tag(:update => "source_title", :url => {:action =>
'update_title'}) do |f|
%p
%label Title:
= text_field :source, :title, :size => 80
= submit_tag "Do AJAX Update"
Now I see the problem. I just copied the "|f|" part from somewhere,
but it doesn't seem to be needed here. If I take it out there error
disappears. And if I leave it in and try to use "f.text_field" then I
get a "trying to evaluate nil" error. Not sure where I got that |f|
business from in the first place.
Thanks,
