I'm not sure about the CFDUMP issues you're having, but declaring CFARGUMENT
actually creates the argument no matter what. When you set required=no
without specifying a default=x, CF automatically sets its own default. If
you don't want the argument to appear when you don't pass it, simply don't
declare the CFARGUMENT tag.
<cfcomponent>
<cffunction name="func" output="true">
<cfdump var="#arguments#" label="f1 arguments">
</cffunction>
</cfcomponent>

Subject: [CFCDev] <cfargument> tag "bug"..?
G'day (again):
And now for why I was putting <cfdump> tags in my functions in the first
place (qv)!
Back to my (now modified back to the original) sample code from my
previous post:
COMP.CFC
<cfcomponent>
<cffunction name="func" output="true">
<cfargument name="arg" required="no">
<cfdump var="#arguments#" label="f1 arguments">
</cffunction>
</cfcomponent>
CALLER.CFM
<cfinvoke component="comp" method="func">
Note I've not passed any args into func().
So why are they showing up? I could understand this if they had a
default value set, but... No.
I've not passed them in: they should not be there.
It's like CF is "helpfully" giving the arguments a default of NULL,
which is a really dumb thing to do seeing CF has no concept of NULL.
But *why* it it creating them at all?
Scratching head.
