Description

trunk/sample/src/main/resources/sports.xsd#834610

1. add in "<xsd:schema" -> xmlns:sdo="commonj.sdo"
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:sdo="commonj.sdo"
xmlns:sdoJava="commonj.sdo/java"
xmlns:sdoXML="commonj.sdo/xml"
xmlns:spt="http://www.apache.org/tuscany/sports"
targetNamespace="http://www.apache.org/tuscany/sports">

2. put sdo:ChangeSummaryType:changes
<xsd:complexType name="SportingUnion">
<xsd:sequence>
<xsd:element name="member" type="spt:Player" maxOccurs="unbounded" />
<xsd:element name="team" type="spt:Team" maxOccurs="unbounded" />
<xsd:element name="changes" type="sdo:ChangeSummaryType"/>
</xsd:sequence>
</xsd:complexType>

trunk/sample/src/main/java/org/apache/tuscany/samples\sdo\intermediate\OppositeProperty.java#834610
3. start logging
DataObject union = unionDoc.getRootObject();
union.getChangeSummary().beginLogging();

RESULT:
<?xml version="1.0" encoding="ASCII"?>
<spt:union xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:spt="http://www.apache.org/tuscany/sports"
xsi:schemaLocation="http://www.apache.org/tuscany/sports sports.xsd">
