Google maps error with Rails 2.3.2

I have been using Google Maps with Rails 2.0.2 and 2.1.0 which works
fine. I followed this tutorial:

Now after upgrading to Rails 2.3.2 I'm getting the following error:
uninitialized constant ActionController::AbstractRequest

on the following line:
<%= GMap.header %>

Has anything changed in Rails 2.3.2 regarding the way Google maps are

Any ideas?



Looks like ActionController::AbstractRequest has morphed to
ActionController::Request, at least most of the methods are there.

I had the same problem. I used the directions to edit the ym4-gm plug
in here:
it worked great for me.
Hope it helps.
