Bob Silverberg just announced the availability of a ColdBox plugin for interacting with his Validate This! framework!  I highly encourage you to test drive Validate This as it is truly an awesome validation framework.  He not only did the plugin but adapted a sample application to work with it.

So if you are still trying to determine validation and want an easy and great solution, give ValidateThis a shot!  Here are some links for you:
