Chris , this could be a problem of the calling code (maybe wpf), since withing a Set we haven't a index for items.. And the event handler of "CollectionChanged" want the index of the item that was remove. You could see the test here: http://digg.com/u1BO0j( removeall_should_raise_collectionchanged_for_removeditems).
I don't know how to set with fluent nhibernate the collection type factory. For the other hand, 100% AGREE with Fabio. For instance the class that Fabio show to you, in "runtime", implements INotifyPropertyChanged and IDataErrorInfo. There is also another behavior for IEditableObject, actually there are two. You could see how I configure the entity http://digg.com/u1BO11 2009/8/25 Fabio Maulo <fabioma...@gmail.com> > what I mean is that you can do the same without that boiled code. > > 2009/8/25 Chris Willard <chris.will...@rimrockgroup.com> > > >> Those interfaces are implemented in my entity base class >> (BindableObject) from which GuidPOCO is derived (Section > GuidPOCO > >> BindableObject).
