One more thing Martin, this solution only works in ColdFusion 10 and Railo, not sure Adobe has it 100% in ColdFusion 10 either. Just in case, take a mental note of the following. If you run into problems like this, also try defining the structure outside of the function/method call.
For example
var myStruct = {};
var test = myFunction(name = ‘something’, args = myStruct);
Most of the issues that happen when passing structs and associative arrays, is because of a bug in ColdFusion itself. Just thought I would mention it, because it could even be as simple as this next time.
