Symptoms
When executing a Stored procedure that creates an entry in a table from a form, if controls that are used as input values are blank, it enters the value "scnull" instead of NULL. This causes extra unnecessary data to be stored in the table.
Diagnoses
When a stored proc has return properties the broker will describe it as a list method. The return "scnull" properties were not handled correctly by the broker.
