I followed the setup from http://cartographer.rubyforge.org/
but keep getting this error -
NoMethodError in Sandbox#map
Showing app/views/layouts/sandbox.rhtml where line #4 raised:
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.
Extracted source (around line #4):
3: Admin: <%= controller.action_name %>
4: <%= gmaps_header %>
Any help would be great! thx
