Ah, but what if you don't want to give the id a default but instead want to give a login page instead. CFPARAM without a default throws an error if the variable does not exist. You can catch that or know that you may have to handle it and do so. In CFMX 6 there was an option to view the pre-compiled java code that your CF template turned into. This was VERY interesting as it showed things like CFIF and IIF() compiled down to the exact same code. I wonder what CFPARAM would compile down to in comparison to some CFIFs and how efficient it is under the hood. Just for knowledge sake. :)
