Hello,

Yep, Edhy, the WPF ICollectionView and IEditableCollectionViewAddNewItem models take care of adding/editing an item when the view is sorted/filtered by holding the item to the side until the add/edit of the item is finalized through CommitAdd/Edit().  There's even a NewItemPlaceholderPosition to allow you to specify whether you want the blank new-item row on the top or the bottom.

Yes, Ben you are right.

I remember long time ago when I was starting with SF having this sort of weird outcome when using filter/sorting on a BO and adding new rows or deleting current one.  Careful is a most during those situation, but I must also say that I love the BO Filter/Sorting features since they have allowed me to deal with some custom processing in an easy way, again as long as I remember that I using a filter or sort later on
