[Rails] uprgrade to 0.10: uninitialized constant Class::Object

[Duane Johnson]

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,
Duane Johnson
