The QueriableCollectionView is not supported in the ScheduleView control yet. The problem is that the ScheduleView is using the collection view to group itself, but the GroupDescriptions used are not supported by the QueriableCollectionView. Unfortunately this problem is very deep into the core of the ScheduleView control and cannot be fixed easily so I cannot give you a concrete time frame when we will fix it, but I logged it in PITS
where you can track its progress.
