Hey,
i am currently upgrading a Rails 2.1 app to 2.3 to benefit from Rails
engines.
The app requires rendering javascript updates to strings, which does
not work
with 2.3 anymore:
data =
ActionView::Base.new(Rails::Configuration.new.view_path).render(:update)
do |page|
page[“div[id=‘foo’]”].removeClass(“bar”)
end
whihc results in an error because the @template variable is nil.
/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.12/lib/active_support/
whiny_nil.rb:52:in method_missing': undefined methodwith_output_buffer’ for nil:NilClass (NoMethodError)
from /usr/lib/ruby/gems/1.8/gems/actionpack-2.3.12/lib/action_view/

…
I am not a rails intern and have problems to follow the @template
variable construction. Has anyone an idea of how to
get the code working again with 2.3?
