Missing Helper file helpers/all_helper.rb ?

Hi,

I have this line in my application.rb controller:

  helper :all # include all helpers, all the time

which in the 1.2.3 Rails Gem environment I'm in, is causing this
error:

We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it
shortly.

and in the log file:

When I remove this line from the log file, everything seems to work.
But this line was auto-generated. What does this mean and is there
something I should be worried about here? - Dave

That's something that was added in 2.0. Are you developing/running with different versions of rails?

Fred

Ah, no. The host is running 1.2.3. - Dave

If you're running 2.0 where you develop (which seems likely given the
autogenerated code), then you're setting yourself up for a world of
pain.
