Question

I created a custom event class, and a EventDispatcher-derived class.
What i did, is putting some logic in my EventDispatcher class, and then dispatched the custom event, the problem is i cant manage to listen to the event from my Main app.

I have an Arraycollection which i create and edit in the main app, than i want to send it to the EventDispatcher , and make a few checks, and than i want to dispatch my ArrayCollection back to main app for Binding with Visual objects.

If my entire code logic is incorrect, please tell me [=

Here is some code

The EventDispatcher sub-class

public class LoadData extends EventDispatcher
{
    public var sendData:DataSender = new DataSender('DataLoader',dataList,true);
    private var dataList:ArrayCollection = new ArrayCollection();           
    dispatchEvent(sendData);
}

The custom Event class

public class DataSender extends Event {
    public var data:ArrayCollection = new ArrayCollection;
    public function DataSender(type:String, data:ArrayCollection, bubbles:Boolean=true, cancelable:Boolean=false)
    {
        super(type, bubbles, cancelable);
        this.data = data;
    }
}

The Main app

var DataEvent:LoadData = new LoadData(dataList);
addEventListener('DataLoader',datacapture);


public function datacapture(event:DataSender):void{
    check.dataProvider = event.data;    
}

You would have to make sure that the event is not dispatched before you actually listen to it. According to your code, it’s not very clear when the event is dispatched.

Without going into the details of your logic, you could probably do something like this, please note that I’m not recommending this implementation, simply illustrating my answer!

    //In the LoadData Class
    public var sendData:DataSender = new DataSender('DataLoader',dataList,true);
    private var dataList:ArrayCollection = new ArrayCollection();   

    public function dispatch():void
    {
       dispatchEvent(sendData);
    }

    //In your Main App
    var dataEvent:LoadData = new LoadData(dataList);
    dataEvent.addEventListener('DataLoader',datacapture);
    dataEvent.dispatch();
