private function onAddTestItemComplete(event : TestCenterEvent):void{
			
	logger.log("onAddTestItemComplet");
			
	var item : TestCenterItem = new TestCenterItem(); // create my view
	item.dataProvider =  event.testItemDataProvider as RequestItem; // add dataprovider 
	mediatorMap.createMediator(item); // create a mediator 
	view.centerContainer.addElement(item); // add it to stage
			
}

I take that somewhere you've done this:

mediatorMap.mapView(TestCenterItem, YourMediatorClass);

Ofcuz in my ApplicationContext i have map my mediator to my view!

ok, yeah sorry on twitter is difficult to explain something in detail.

what I ended up doing is the following:

var myViewInstance:MyViewClass = new MyView();

mediatorMap.mapView(MyViewClass , MyViewMediator);

mediatorMap.createMediator(myViewInstance);

injector.mapValue(MyViewClass, myViewInstance);

as mentioned on twitter I set myViewInstance as a Singleton via the mapValue method so to have one instance throughout the app.
