Dear Keith Visco:
This is the third time I post the
message.
I am in great trouble.
I have described the problem in details in last two
times.
=================== Last time message
==============
:::
has castor-xml implemented the complex type's
extension functionality in the marshall/unmarshall framework?
the source generator remarkably did
this.
that is: we have xsd (partial)
<xs:complexType name="SubType">
<xs:complexContent>
<xs:extension base="SuperType">
<xs:sequence>
<xs:element name="rootElement"
type="xs:string"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:complexType
name="SuperType">
<xs:attribute name="id"
type="xs:string" />
</xs:complexType>
then we unmarshall from xml:
<SuperType id="2"
xsi:type="SubType">
<rootElement>order</rootElement>
</SuperType>
in the current cvs version
of castor-xml.
we cannot cast the got
object from SuperType to SubType.
I think that is want we want to do by
design.
When I unmarshalled using the generated
descriptors. I got the following exception:
org.xml.sax.SAXException: unable to find
FieldDescriptor for 'rootElement' in ClassDescriptor of SuperType.
at
org.exolab.castor.xml.UnmarshalHandler.startElement(UnmarshalHandler.java:815)
at org.apache.xerces.parsers.SAXParser.startElement(SAXParser.java:1340) at
org.apache.xerces.validators.common.XMLValidator.callStartElement(XMLValidator.java:1197)

I am anxiously waiting for the help.
e.g. how can i modify the generated descriptor to solve this
problem..... =================================
This time I attached the files I used in my
test.
please help
