Bryan, what you're missing here is that an unrecognized type has to be a
CFC. You'd have a SpecialNumber.cfc file in your CFC directory.
specialnumber.cfc
<cfcomponent displayname="SpecialNumber">
<cfset variables.instance = StructNew() />
<cfset variables.instance.data = 0 />
<cffunction name="setValue" returntype="SpecialNumber">
<cfargument name="newNumber" type="numeric">
<!--- validation... --->
<cfset variables.instance.data = arguments.newNumber />
<cfreturn this />
</cffunction>
<cffunction name="getValue" returntype="numeric">
<cfreturn variables.instance.data />
</cffunction>
</cfcomponent>
someother.cfc
<cfcomponent displayname="Some Other Component">
<cfset variables.instance = StructNew() />
<cfset variables.instance.someNumber = CreateObject("component",
"cfcpath.to.specialnumber") />
<cffunction name="setSomeNumber" returntype="boolean">
<cfargument name="newNumber" type="SpecialNumber" />
<cfset variables.instance.someNumber = arguments.newNumber />
<cfreturn true />
</cffunction>
</cfcomponent>

Subject: RE: [CFCDev] Custom argument types
I know that. Regarding item 4.
"You could also make a CFC, SpecialNumber. When you create it, you pass
in the #. The CFC handles all the silly checking."
cfc2
<cfcomponent>
<cffunction name="specialNumber" access="public"
returntype="???">
<cfargument name="theNumber" required="yes"
type="numeric">
<cfset var specialNumberReturn=''>
<cfscript>
if(arguments.theNumber gt 5) {
specialNumberReturn=true;
} else {
throw('This CFC will self destruct
in...');
}
</cfscript>
<cfreturn ?????>
</cffunction>
</cfcomponent>
" If another CFC wants to use a method and require that type of value,
then you would just use type="SpecialNumber" for your cfargument tag.""
cfc1
<cfcomponent>
<cffunction name="yaddaDoodle" access="public"
returntype="boolean">
<cfargument name="theSpecialNumber" required="yes"
type="specialNumber">
....
</cffunction>
</cfcomponent>
How does CFC 1 know where to look for CFC 2?
