If you look at http://livedocs.adobe.com/coldfusion/7/htmldocs/00000218.htm (cfargument tag), in the description of "type" the table of attributes you'll see the very last point says:- a component name: if the type attribute value is not one of the preceding items, ColdFusion treats it as the name of a ColdFusion component. When the function executes, it generates an error if the argument that is passed in is not a CFC with the specified name. Remember, when you create an instance of a cfc, cfdump will tell you the name of underlying cfc. So when you state that the type is of a specific cfc, cf will validate the type of the instance against the type required in the cfargument tag. > <cfargument name="myList" required="No" type="MyNurmericList" /> > > ---CFC-- > <cfcompoent> > // what goes in here? > </cfcomponent> Firstly properties to store the value of the numeric list and secondly methods to set, validate and retrieve a numeric list > Or do you call it like.... > > <cfargument name="myList" required="No" > type="#MyNurmericList.isValid(arguments.myList)#" /> No, the value of type must be the name of a type as a string. > This is the bit I don't get because usually you would call a method in the > CFC but the docs say they custom type is a reference to a CFC Since the type attribute is optional, you can pass anything and no errors are generated. If specify the type attribute, the value you pass it must of that type of an error is generated due to the type mismatch.
