Java Service [message #1860882]

Hi community !

I'm trying, with no success so far, to get a functional Java Service in my odesign project.

I'm pretty sure that my service is correctly registered, because the autocompletion works and propose the methods that I've written. Also, if I suppress the Java extension declaration, the validation tells me that the services can't be found.

But.

But nothing happens then. For example, I have a simple Task concept with an attribute 'name' and the service below returns nothing:

public String getTaskName(Task task) {
    	return task.getName();
    }

or when I try to calculate a collection, it seems to return nothing:

    public List<Task> getAllTargets(Task task) {
      List<Task> targets = new ArrayList<>();
      targets.add(task);
      return targets;
    }

Have anyone have a clue about what I've missed ?

Thx

Hi,

The code for the service methods seem fine, so the problem is probably elsewhere.

How do you invoke these in your odesign?

Hi Pierre-Charles,

for example, on a Relation Based Edge whose Source and Target mappings are 'Task node', I'm trying to use the getAllTargets() service in the 'TargetFinder Expression' with
