I''ve seen this before - it''s typically a sign that something
has
screwed up the inherited callback for AR::Base. And a quick look at
the rubycocoa source shows this:
(in
http://rubycocoa.svn.sourceforge.net/viewvc/rubycocoa/trunk/src/framework/src/ruby/osx/objc/active_record.rb?revision=2232&view=markup
class ActiveRecord::Base
class << self
alias_method :__inherited_before_proxy, :inherited
def inherited(klass)
proxy_klass = "#{klass.to_s}Proxy"
unless klass.parent.local_constants.include?(proxy_klass)
eval "class ::#{proxy_klass} < OSX::ActiveRecordProxy;
end;"
# FIXME: This leads to a TypeError originating from:
oc_import.rb:618:in `method_added''
# Object.const_set(proxy_klass, Class.new
(OSX::ActiveRecordProxy))
end
__inherited_before_proxy(klass)
end
end
There''s something going on, but I''m not clear why this would
cause a
problem. You might do better asking on a rubycocoa list...
