just uploaded a new release of AjaxCFC with a couple of fixes:
- backwards compatibility for single arguments with an object, provided by nathanael waite. You may add the setComplexInputStruct(boolean) to the top of your function to enable or disable allowing argumentCollections to be passed to ajaxCFC. If enabled and a single object is passed as an arguments, it will be threaded as a collection. This is enabled by default.
- fix in the argumentCollection option mentioned above to allow passing a single array argument.
