We're using Castor XML sourceGen to generate Java code corresponding to an XML schema that has abstract complexTypes and extensions. In our example, the base schema contains a sequence, and the extension class attempts to add a choice to the end of the sequence. We get a validation error if we attempt to add both the element from the base schema and one of the choices from the extension.
Just in case it was a problem with our extension complexType, we also tried wrapping the <choice> in a <sequence>, to make it match the base type. The problem was reproduced with the CVS version as of Dec. 6/2001. <schema targetNamespace="http://www.namespace_check/extensionSchemaTest.xsd"; xmlns="http://www.w3.org/2001/XMLSchema"; xmlns:nsthree="http://www.namespace_check/extensionSchemaTest.xsd";> <complexType name="ThreeAbstractType" abstract="true"> <sequence> <element name="StringOne" type="string"/> </sequence> </complexType> <element name="Three" type="nsthree:ThreeType"/> <complexType name="ThreeType"> <complexContent> <extension base="nsthree:ThreeAbstractType"> <!-- could start a <sequence> here --> <choice> <element name="StringTwo" type="string"/> <element name="StringThree" type="string"/> </choice> <!-- could end the </sequence> here --> </extension> </complexContent> </complexType> </schema> -------------------------- Main Program: -------------------------- java.io.StringWriter sw = new StringWriter(); Marshaller debugM = new Marshaller((java.io.Writer)(sw)); debugM.setNamespaceMapping("nsthree", "http://www.namespace_check/extensionSchemaTest.xsd";); Three three = new Three(); three.setStringTwo("string two"); three.setStringOne("string one"); debugM.marshal(three); StringBuffer buff = sw.getBuffer(); debug(buff.toString()); -------------------------- GeneratedException: -------------------------- ValidationException: The element 'StringTwo' cannot exist at the same time that element 'StringOne' also exists.; - location of error: XPATH: Three Irving Reid Principal Technical Architect, SelectAccess Baltimore Technologies ----------------------------------------------------------------------------------------------------------------- The information contained in this message is confidential and is intended for the addressee(s) only.
