Og manages classes that define serializable attributes. A serializable attribute is an attribute with a class annotation. This works great for 95% of the cases. For the rest, you can use Og features like the following to customize the behaviour, including: class XXX is Unmanageabke end or class XXX attr_accessor :test, String, :serializable => false end etc, etc. regards, George. -- http://www.gmosx.com http://www.nitroproject.org
