Not sure why that test is failing, everything is green locally. 🤔 |
ObservableCollection<T> is designed soNotifyCollectionChangedEventArgs.OldItems is not populated when .Clear()is called on the collection. Because of this, Caliburn conductors can'tunset the Parent property on all conducted IChild.There are multiple solutions to this issue that have been discussed, butI feel like adding a new CollectionCleared event to BindableCollectionis the best compromise considering it doesn't break any existing codeand only extends existing ObservableCollection functionality.

ObservableCollection is designed so
NotifyCollectionChangedEventArgs.OldItems is not populated when .Clear()
is called on the collection. Because of this, Caliburn conductors can't
unset the Parent property on all conducted IChild.
There are multiple solutions to this issue that have been discussed, but
I feel like adding a new CollectionCleared event to BindableCollection
is the best compromise considering it doesn't break any existing code
and only extends existing ObservableCollection functionality.
Fixes#465
