Angular 2 @Output parameters

Question

Im trying to pass parameters through @Output but the fired function just receive 'undefined'. Can someone please show me the way to pass parameters through the EventEmitter of the @Output? For Example:

var childCmp = ng.core.Component({
             selector:'child-cmp',
             outputs: ['myEvent']
             }).Class({
               constructor: function(){
                            this.myEvent = new ng.core.EventEmitter();
                            this.myEvent.emit(false);
                            }
             });
var parentCmp = ng.core.Component({
              selector:'parent-cmp',
              template:'<child-cmp (myEvent)="invoke()"'></child-cmp>',
              directives: [childCmp]
           }).Class({
                constructor:function(){},
                invoke: function(flag){
                    // here flag is undefined!!
                }
             });

Answer 1

You shoud use the following to get the value provided with the event:

<child-cmp (myEvent)="invoke($event)"'></child-cmp>'

This way the invoke method of your childCmp will receive as parameter the value you provide when emitting the myEvent custom event.

Hope it helps you, Thierry
