> I cant get Changesummary on a datagraph working correctly with the following
> contents: (hope this is a realy a bug this time)
> Schema, generated by the xsdhelper:
> <xs:schema
> xmlns:sdo="commonj.sdo" xmlns:sdoJava="commonj.sdo/java"
> xmlns:stn_1="http://example.com/customer";
> xmlns:xs="http://www.w3.org/2001/XMLSchema";
> attributeFormDefault="qualified" elementFormDefault="qualified"
> targetNamespace="http://example.com/customer";>
> <xs:complexType abstract="false" name="Account">
> <xs:sequence/>
> <xs:attribute default="0" name="accountNum" type="xs:int"/>
> </xs:complexType>
> <xs:element name="account" type="stn_1:Account"/>
> <xs:complexType abstract="false" name="Customer">

> </xs:sequence>
> <xs:attribute name="firstName" type="xs:string"/>
> </xs:complexType>
> <xs:element name="customer" type="stn_1:Customer"/>
> </xs:schema>
> After generation of interfaces the following code fails to work as I would
> expect, because the changesummary does not contain the changed dataobject in
> the graph.
