Brian,
Though a valid concern, just wanted to make it clear that the
deserialized cfc will not go out of sync when a new method is added
while it was serialized. This is because, the methods are never
serialized. It's only the instance level data associated with the cfc
instance, such as the variables in the this scope and in the var scope
of the cfc, that get serialized. The methods are always available in the
cfc template. Hence, the methods are not serialized.
So, once the cfc instance is back into action when it is deserialized,
the new methods will be available to the cfc from the .cfc template.
The best part about CFC serialization is it can handle complex circular
references as well. That is, if a cfc has a reference back to the itself
in the this scope, then you can expect the same circular reference to be
maintained once the cfc is deserailized.
And yes, we are working on the serializing array and query objects
within the cfc scopes. That issue will be fixed soon.
Thanks,
Rakshith

Also, be very careful because if you have serialized versions of CFCs in
the
database and then you change the actual code for the CFC (add a method,
etc.), you are going to have major problems because your application
code
will be out of synch with the serialized CFCs. Which means if you add a
method and then deserialize the CFC, at best any code in your app that
uses
the new method will blow up when it hits your out-of-synch deserialized
CFC,
and at worst it might not even deserialize at all.
