Using the field calculator from the attribute table, the $area of each feature is shown nicely in the table until I try to save it, then all the values are replaced by NULL so are no longer available for use for labels or other calculations. Furthermore, if the column is left there and the field calculator asked to update it, all values remain NULL; the column has to be deleted and re-added.
