I'm the developer of Rails Footnotes plugin and I need to know the location of the template being rendered.
I've put a debugger at the end of process method on ActionController::Base, and then called:
@template.template
Which returned nil, Since the template method give me the last object in the @_render_stack variable, I've checked and I can't actually see where the @_render_stack is being filled. It's always empty.
Ticket is here: http://rails.lighthouseapp.com/projects/8994/tickets/1884-actionviewbase-_render_stack-is-not-being-filled-on-edge
