Hi Matt, As you know we use a lot of webservices with Razuna and one thing that always hits me is that functions which are declared with access=remote also requires that all parameters are being passed in. The "required" true/false has no effect.
This is something that Adobe Coldfusion documents also point out in "Publishing Webservices" at http://livedocs.adobe.com/coldfusion/8/htmldocs/webservices_01.html. Point 4: The attribute setting required="false" for the cfargument tag is ignored. ColdFusion considers all parameters as required.
