Hello everybody,
i created a new method in the Services.java. I wondered why it doesn't return what i expected. So i tried do create a method that just returns a String:
index.php/fa/28446/0/

when i use these method like this:
index.php/fa/28447/0/

the "Name" of the node is empty;
when i use the method like this:
index.php/fa/28448/0/

i can't create a node.

Can someone help me? I don't know what i'm doing wrong.

Regards,
Tobias

Hi Toblas,

The service method is composed least 1 parameter. This parameter correspond to the context of service call. So, in your service you must have one parameter for context and one parameter for the argument.
You should have
public String getType (EObject context, String name){
return name;
}

If you use the simple interpreter as "service: "
you can't pass a String parameter for service call. "Service:" is only used with Sirius variables defined in tool.
In your case you must use aql:self.getType('abc')

Regards,
