Description

The SDO for Java 2.1 spec states this about the getSequence() behavior in section 3.1.1:

3. Sequenced. A DataObject is similar to a JavaBean plus it has order within and
across Properties. In XML this is equivalent to a DOM. When using XML, a
Sequence (see Sequence) represents the order of all the XML elements in the
DataObject. Values are available through get(property) but order across Properties
is maintained through the Sequence interface. getSequence() returns a Sequence
of the XML elements for the case of XML. XML Attributes do not have the
concept of order and are accessed through get(property).

Currently, the code is returning a null, rather than an empty Sequence object. I'll attach a sample application to demonstrate the problem.
