Yes, this is a very serious bug - it nixes your content tags in rails
2.2.
Before I saw this post I came up with my own fix, but in
capture_with_haml and not in content_tag_with_haml.
This fix is shorter - I just changed line 96 of action_view_mods.rb
from this:
if is_haml?
to this:
block_is_haml =
begin
eval('_hamlout', block)
true
rescue
false
end
if block_is_haml && is_haml?
