Setting journal folder currentview problem

Anyone have any idea why this has no effect on the folder view?

  myFolder=NS.PickFolder
  If myFolder.DefaultItemType = 4 Then
     myFolder.CurrentView = "Last Seven Days"
  End If

Everything else I do (get EntryID and StoreID etc) with the myFolder
object in this sub works so I do have the folder reference.

Thanks
