I have a ReportView mapped as singleton in AppConfig.

Then in MainView,
[Inject]
public var injector:IInjector;
[Inject]
public var pageReport:ReportView;

injector.unmap( ReportView );
pageReport = injector.getOrCreateNewInstance(ReportView);
oNewContent.addElement(pageReport);

How come i always get error when i minimize the window:
Warning: Injector already has a mapping for com.nielsen.catcast.report.view::ReportView|.
 If you have overridden this mapping intentionally you can use "injector.unmap()" prior to your replacement mapping in order to avoid seeing this message.

   Hello,

   It looks like you have more than one mapping for your ReportView.
   I suppose that you are mapping the view to a mediator as well. Maybe you have 2 mappings for your ReportView, like these:

   injector.map(ReportView).asSingleton();

   and

   mediatorMap.map(ReportView).toMediator(ReportMediator);

   So, one mapping overrides the other, and that's why you're getting the error.
   To avoid this, you could use the ViewProcessorMapExtension instead of the mediatorMap:

   viewProcessorMap.map(ReportView).toProcess( new MediatorCreator(ReportMediator));

   Let me know if that solves your problem.

   If that's not your use case, then you should provide more info. Show us your code where you perform the mappings. Or, you can attach your project or a simple example reproducing the issue as a zip file, and I'll take a look at it.
