My opinion is that a Bean should be able to validate itself to ensure that it hold valid data. However, it is common for validation to be wrapped up into another object that the Bean uses (or gets passed into) which actually does the validation. Especially since a lot of validation code can be reused across many Beans (using a list of required properties, a list of valid property values, etc.).
Beans should be clever. I think people view Beans as nothing but data containers with getters and setters for properties. Technically that is the definition of a Bean, but a good Business Object can be a Bean (because it has getters and setters for properties) and still do much more than simply hold data. I'm not sure what you mean by "business logic that isn't related to the DB or the other CFCs".
