My example left out the default. If a CFPARAM exists with a name but no default, it throws an error if the variable does not exist. i.e. it's saying that the variable has to exist. If I read your idea right, any error will result in the default being used so if myID is a string, rather than an error we'll get a value of 0 for the variable. My idea makes the handling of the error something that can be coded where your approach forces a default value on error. It also doesn't address when the tag is used without a default.
I actually have to email you. I moved your mail to a "must reply" folder which is top of my list to do.
