(BUG in svn/trunk?) - superclass mismatch for any subclass o

I track svn/trunk of Rails using svn:externals

Some change to Rails committed in the last 1-2 days broke my subclass
of ApplicationController

The example, below, works with Rails 1.0, but in today’s svn, it dies
with the following error:

“superclass mismatch for class FooController”

class ApplicationController < ActionController::Base
end

class FooController < ApplicationController
end

The reason I’m emailing the list instead of filing a bug report is to
see if anyone knows if this change was intentional. I hope not,
because I really do need to have a subclass of ApplicationController.

Any advice appreciated.

Hello Miles,

2006/2/3, Miles K. [email protected]:

I track svn/trunk of Rails using svn:externals

I do the same.

Some change to Rails committed in the last 1-2 days broke my subclass
of ApplicationController

Actually, I tracked it down to r3524. If I load r3523, my app works
fine, if r3524, I get the following backtrace:

This is a different bug than yours, but it seemed related enough that
I’d mention it here.

Bye !

I could swear I saw this exact problem on the list in the last week or
so… give the
archives a search…

Any advice appreciated.

Yep, trunk is broken at the moment. For now I’d suggest rolling back
to revision 3479.

To do this, run “svn propedit svn:externals vendor” from your
application’s directory. Then change the line that reads

rails Peak Obsession

to

rails -r3479 Peak Obsession

and svn up.
