Inheritance problem, instance gets always super type

 Hi , instance gets always super type


Hi,
 
I have a problem using xmlbeans with inherited types with java. In my commons.xsd there is a complex type Operation and some other types which are extending Operation. In a MoreSpecifix.xsd is commons.xsd imported and a complex type Config is declared. This type Config does declare a sequence of Operation. So it should be possible to add all types which extend Operation to the sequence in Config.
 
After the generation of the java classes I run into the following problems:
 
First try:
final ConfigDocument configDocument = ConfigDocument.Factory.newInstance();
final Config newConfig = configDocument.addNewConfig();

final Operation[] ops = new OperationType[1];

ops[0] = createConcreteOperationDummy();

newConfig.setOperationArray(ops);

With the last line my concrete operation instance gets the type from the super class Operation and I can no more access the extended fields.

Second try:

final ConfigDocument configDocument = ConfigDocument.Factory.newInstance();

final Config newConfig = configDocument.addNewConfig();

final Operation newOperation = newConfig.addNewOperation();

final ConcreteOperation concreteOp = (ConcreteOperation) newOperation.changeType(ConcreteOperation.type);

On the last line I get a ClassCastException. 

Has someone an idea what is wrong ? Probably the xsd definitions (made with XMLSpy) ?

Regards,

Oliver
