uprgrade to 0.10: uninitialized constant Class::Object

Hi,

I installed rails 0.10 with ruby gem, and upgraded my application as
described at http://manuals.rubyonrails.com/read/book/15 .

Now, when accessing the action index of the controller rss_feed, I get
this error in the terminal when I started the server:


#<NameError: uninitialized constant Class::Object>

The rails server is listening on port 3082.
It''s behing an apache proxy with this config:

        ProxyPass         / http://127.0.0.1:3082/
        ProxyPassReverse  / http://127.0.0.1:3082/

I access the url http://servername/rss_feed/index
Running on debian, with all ruby1.8 packages installed.

Any idea?

Thanks

Re: uprgrade to 0.10: uninitialized constant Class::Object

Raphael:

I had a similar problem (couldn''t find String or Array) when
upgrading.  I discovered in my case that it had to do with some custom
modifications I had made to the Ruby classes.  In Rails 0.10 the
workaround seems to be to put any such modifications in the helper
classes (such as ApplicationHelper.rb) or else to open built-in
classes with "class Object::Array" instead of "class Array"
as I had
been used to doing.

I know this doesn''t solve your problem directly, but it may lead to
something helpful :)

Take care,

By the way, this quirky behavior is fixed in 0.10.1.

It didn''t solve my problem immediately, but it led me to the solution.
I had a deep_copy method defined.

Thanks for your help!
