Public Function NewList() As List
If KeepHierarchical is true, NewList returns a HierarchySupportList, containing the roots of trees that contain at least one item that meets the filter criteria.
If KeepHierarchical is False, NewList returns a FactoryList Object.
If you call NewList more than once on the same filter, no actual server request is made. NewList returns cached data.
To retrieve data that may have changed, either dispose of the filter and create a new one, or call Refresh before calling NewList.
