Nolan,

That's from an article I did for oreilly.com a while back:

http://www.oreillynet.com/pub/a/javascript/2003/09/24/coldfusion_tips.html?page=1

As far as I know, it isn't a bug. I don't know the WSDL 1.1 spec well enough to answer 
whether it is a function of that design, or specific to Axis.
However, I haven't come across any web services yet that support optional arguments.

-Rob

Subject:    [CFCDev] Apache does not support optional parameters???


A co-worker just found the following documentation (i'm not sure where
exactly):

6. Watch Optional Arguments
If you plan to expose your CFCs as web services, be careful with optional
arguments. The Apache Axis 1.1 web services engine used by ColdFusion MX
6.1 does not support optional input arguments. If your CFC methods contain
optional arguments, the required attribute setting is ignored, and the
argument is treated as required. Here's an example:
<cfcomponent>
  <cffunction name="getMessage" access="remote" returntype="string"
    output="no">
    <cfargument name="name" type="string" required="no" default="Stinky">
    <cfreturn "Hello " & arguments.name &"! " & "I've been invoked as a web
              service.">
  </cffuntion>
</cfcomponent>
In this case, even though name is an optional argument as far as the CFC is
concerned, it is required when you expose it as a web service. If you try
to call the component method as a web service and don't provide a name
argument, ColdFusion throws an error.
--------------------------
that sounds like either a fairly big bug to me, or something we can easily
work around with a particular coding style that we're just not using here
(yet).  Has anyone else experienced this?  Any insight on preferred ways to
deal with it?

Thanks,
Nolan
