Error in tools.cmpObjects if one of the objects to compare is null instead of a String.
This error causes that in UCS@school e.g. the column 'Class' in the Users wizard is not sortable so that one get the error message "Es ist ein Fehler aufgetreten" in the grid instead of grid entries.

Exception: TypeError: Cannot read property 'toLowerCase' of null

Fix is simply:
