Hi all,
I updated Rails to 1.1.1 and engines to 1.1.1.
Since then, my cache sweepers stopped working.
I get this error:
You have a nil object when you didn't expect it!
The error occured while evaluating nil.controller_name
See end of post for full error trace.
When I move the controller from vendor/plugins/myengine/app/controllers
to app/controllers, everything works fine, so I guess it's an engine
bug.
Controller:
class TestController < ApplicationController
layout false
helper :admin_pages
model :page_element, :element_sweeper
cache_sweeper :element_sweeper
def test
render :inline=>"blaa"
end
end
Sweeper:
class ElementSweeper < ActionController::Caching::Sweeper
observe PageElement
end
Errors:
NoMethodError (You have a nil object when you didn't expect it!
The error occured while evaluating nil.controller_name):
