at the top of my controller, outside of any method, I have

    @@javascript_is_disabled = false

and I have methods that that the view calls and invokes something like this

    @@javascript_is_disabled = params[:javascript_disabled]

but when I need the @@javascript_is_disabled in completely different method.. it is always false.

I know it changes in the method with params args... cause those methods behave differently, and appropriately

And ideas?
