If you use positional parameters, only parameters at the end can be left off. However, you can use named parameters without using CFINVOKE:
<cfset o.method(name=url.name, age=url.age, ...) /> I generally prefer to not specify a default for my option arguments, and then use structKeyExists() against the 'arguments' struct to check if they were passed. Since we don't have method overloading in CF, optional parameters (and their associated conditionals) are a necessary evil. cheers, barneyb On Wed, 1 Dec 2004 10:20:27 +1100, Paul Wilson <[EMAIL PROTECTED]> wrote: > I'm using createObject to invoke a CFC and one of the methods in the CFC > takes a number of arguments, all numeric but not all required.
