[castor-user] unmarshalling equally named/xpath differing elements fails with classcastexception

[Reinhard Weiss]

hi,

i have an top level (document) element 'A' bound to java class 'TopLevelA'.
further there is a nested element named 'A' as well, which is bound to 
'NestedA'.
(yes, the model is stupid, but i can't change...)

on unmarshalling i get a 'NestedA' object instead of the expected 'TopLevelA'.

i am using the 1.2.1-20080723.084025 snapshot available for download.



in xsd that is:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns:xyz="http://www.xyz.com/"; targetNamespace="http://www.xyz.com/"; 
elementFormDefault="qualified" attributeFormDefault="unqualified">
        <xsd:element name="A" type="xyz:SomeType"/>
        <xsd:complexType name="AnotherType">
                <xsd:simpleContent>
                        <xsd:extension base="xsd:string">
                        </xsd:extension>
                </xsd:simpleContent>
        </xsd:complexType>
        <xsd:complexType name="SomeType">
                <xsd:sequence>
                        <xsd:element name="A" type="xyz:AnotherType" 
minOccurs="0" maxOccurs="unbounded"/>
                </xsd:sequence>
        </xsd:complexType>
</xsd:schema>



the xml could be

<?xml version="1.0" encoding="UTF-8"?>
<xyz:A xsi:schemaLocation="http://www.xyz.com/ A.xsd" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns:xyz="http://www.xyz.com/";>
        <xyz:A>hello world</xyz:A>
</xyz:A>



the corresponding castor binding, which i wrote is:

<?xml version="1.0" encoding="UTF-8"?>
<binding xmlns="http://www.castor.org/SourceGenerator/Binding"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xsi:schemaLocation="http://www.castor.org/SourceGenerator/Binding 
http://castor.org/binding.xsd"; defaultBindingType="element">
        <package>
                <name>com.xyz.model</name>
                <namespace>http://www.xyz/</namespace>
        </package>
        <elementBinding name="/A">
                <java-class name="TopLevelA"/>
        </elementBinding>
        <elementBinding name="/complexType:SomeType/A">
                <java-class name="NestedA"/>
        </elementBinding>
</binding>



the test fails:

    URL castrCdrUrl = 
getClass().getClassLoader().getResource("com/xyz/model/.castor.cdr");
    assertNotNull(castrCdrUrl);
    assertTrue(castrCdrUrl.toString().contains("classes"));
    assertTrue(new File(castrCdrUrl.toURI()).exists());
    
    XMLContext context = new XMLContext();
    context.addPackage("com.xyz.model");
    Unmarshaller unmarshaller = context.createUnmarshaller();

    InputStream xmlStream = 
getClass().getClassLoader().getResourceAsStream("A.xml");
    assertNotNull(xmlStream);
   
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    InputSource is = new InputSource(xmlStream);
    Document xmlDocument = builder.parse(is);

    TopLevelA topLevelA = (TopLevelA) unmarshaller.unmarshal(xmlDocument); // 
<- classcastexception
    
    assertNotNull(topLevelA);
    assertNotNull(topLevelA.getNestedA(0));
    assertEquals("hello world", topLevelA.getNestedA(0).getContent());

        

is this an issue to be reported via jira?
