Every time I hear that I get a little twitch going on in my neck (ala the prison gauard in the Life of Brian). A group of functions in a component is still OO. An object does not have to have state. Conversely, an object does not have to have methods and can simply be a set of public fields (for example a representation of a garden gnome - it doesn't do anything but it has state). However, I would bet that in many cases these stateless objects could be given state to be more useable and reusable. For example, lets say we had a component that was a group of functions that returned queries from the database - perhaps they are all queries about garden gnomes. Having no state, the datasource properties could either be hard coded into each cfquery (eek), retrieved from the request/application/session scopes (even more eek), passed to each method as an argument (fine but a bit hard work). By introducing state to the object however, you can set the datasource the first time you get an instance of the component and then never have to worry about it again (unless you are using multiple datasources which I imagine would be rare in such a situation). The component is then self contained and as such is more reusable. Anyways, I think it is all about understanding. The more you can understand, the more use you can get. Why buy a super dooper fast computer and refuse to learn anything but how to check your email? Just having a basic understanding of OO for ColdFusion is going to save a lot of confusion in learning about CFCs and I believe will actually make learning them faster.
