I'm currently developing an application using Parsley 2.3.2 and Cairngorm 3 libraries. My main application view has nested viewstacks and I use Cairngorm navigation library to navigate between the views. The navigation to the nested views works fine, and deferred views are being instantiated properly. However as soon as I add the Enter/Exit handlers to my presentation models, the navigation to my nested views stops working. It always redirects me to the first child of the ViewStack containing the target view. Though the Enter/Exit handlers for my nested view are executed. After I remove Enter/Exit methods, everything works fine again.
