I've defined a custom meta-model using EMF Ecore and now I'm writing an acceleo project to generate proper java code.
Acceleo is not enough for several use cases, mainly searching the model for specific elements and holding extra information for some, so I need to call a custom Java service, and I followed the step-by-step example and I believe I know exactly how to write a query to invoke a Java service.
The problem is that when I call a service with Java primitive parameters it runs smoothly but when I write one with meta-model types I get the following error:

Anyone knows what's wrong?
here's the java code:
public void f(CustomAction c){
}
here's the mtl code
[query public f(arg0 : CustomAction) : OclVoid
= invoke('converter.services.ActivityServices', 'f(metamodel.CustomAction)', Sequence{arg0.oclAsType(CustomAction)}) /]
