Since all the instance level data will be serialized, the deserailized instance should regain the exact state of the instance before it was serialized. However, if the data in either the THIS scope or the VARIABLES scope is modified while the data was serialized, the modified data will not be available in the deserialized instance.

Thanks for the clarification, and that makes sense. Perhaps more to the point though, what happens if you change the actual instance data that your CFC contains (adding or removing a pointer to another component for instance)? I would assume that this will indeed cause things to break, correct?
