Cant add custom class to Services method [message #1835273]

Hi!
I'm having a problem calling java services from diagrams.

I have this test method:

 public String sampleService (EObject obj) {
       return "Foo";
 }

And when I call it from the diagram from a label of my node of domain class "City", it works no problem!

(FYI: when i sysout(obj.eClass() i get CityImpl)

But if change the code to:

 public String sampleService (City obj) {
       return "Foo";
 }

Eclipse can't find sampleService.
Does anyone know what happens and how to fix this?

Update: I've now tried the same with the sample project from Sirius and i still have the same problem.

I created two methods in the org.eclipse.sirius.sample.basicfamily.advanced.design.Services

public String testServiceObject(EObject object) {
		return "Foo";
	}
	
	public String testServicePerson(Person person) {
		return "Bar";
	}

And added them to the label cols in the person table.
Father label expressions: service:testServiceObject
Mother label expressions: service:getCousinsNumber
Children label expressions: aql:self.testServicePerson()
Cousin label expressions: service:getCousinsNumber()

(service:getCousinsNumber is the same as in the solution)

But it is only testServiceObject that returns anything.
