Declaration

C#

public class DuplicateKeyPropertyException :
    Exception

    Inherits Exception

Remarks

This exception is thrown whenever a class with multiple key property definitions is used.

Solution:

- declare only one key property in a persistent object;

- for classes derived from the XPObject class do not declare key properties, as the XPObject already contains the XPObject.Oid key property.
