Same child view-model can't be used two times in parent view-models

When We use the same child view-model that represents some part of other view-model more than one time, it will cause Unable to cast object exception.
E.g Exception like this was raised, when VM RoutingItemPage was used in both AllRoutesPage and RoutingPage:

System.InvalidCastException: Unable to cast object of type 'BlendingEditor.Website.ViewModels.RoutingPage' to type 'BlendingEditor.Website.ViewModels.AllRoutesPage'.
