    Remarks

    Using this method, a client can show a list of values for the user to choose from.

    Specifying the view (and not just a field name) for which values are to be listed is necessary because list of values can depend on the field's format (for example, values can be rounded).

    Clients need to be aware that getting value list can take considerable time if number of rows in the source data is very large.
