this.createObjectData((function(x, y) {
        let jsonObject = getJsonForElement(
          'STORMCASE.UML.ucd.Actor, UMLUCD',
          { x, y },
          { width: 25, height: 50 },
          { Name: '' }
        );
        let usecaseActorObject = fdUseCaseActor.create({ primitive: jsonObject });
        this._addToPrimitives(usecaseActorObject);
        return usecaseActorObject.JointJS();
      }).bind(this), e);
    },
