Description

This tag builds a list of objects that meet the specified criteria. The criteria are a list of name/value pairs, which must be present in the object. The implementing class must implement a list method. The list method should have one of the following prototypes:

• public static IList List (ICS ics, FTValList aArgument, String sOrder)

• public static IList List (ICS ics, FTValList aArgument, String sOrder, String sArg1)

Error Numbers

The possible values of errno include:

Value	Description
-101	No rows returned.
-105	Database error.
-10001	The implementing class is invalid.
-10002	There is a missing method for the implementing class.
-10003	The method could not be invoked successfully.
-10004	A required parameter is missing.
-10010	Invalid attribute value.
