[coldbox 3.5.3] overriding validateModel() in controller decorator

How can I override the validateModel method, available in the controller, using the decorator?

It seems that my application is not mixing in methods in the decorator.

this is in the config:

controllerDecorator = “com.common.decorator.controllerDecorator”

and if i change the path to something invalid, it throws and error.

I use the decorator in other applications w/o a problem.
