Regarding this.validate, I'm writing abstractly to refer to validating an object's data within the object as opposed to sending it out to a separate validation object. You won't find this in any manual.
Back when CFCs first came out I extensively researched how best to handle function libraries since I was creating a very high profile, high traffic, mission critical Web application. I was trying to make use of CFCs extensively because I saw that as the direction CF was headed and it was the hot new feature. My conclusion was that CFCs treated as function libraries incurred unnecessary overhead while offering no additional benefit over a pre-CFC function library. With CF8 things are different in that CFCs in CF8 are much faster, plus they play nice with technologies such as AJAX and Flex. Going back to your original question, you can pass the form structure into a CFC function if you want to. It still seems strange to me, but many decisions in CF come down to personal preference. -Mike Chabot On Sat, Nov 1, 2008 at 5:49 PM, Rick Faircloth <[EMAIL PROTECTED]> wrote: > You're right, Mike... > > I'm just using the CFC as more of a function library, not so much from > an OOP standpoint.
