[jboss-user] [JBossWS] - JAXB error when using different derived types in the same co

I have what seems to be a correct piece of SOAP being sent to JBossWS 1.0.4 that causes a binding exception. This only occurs when I send 2 different sub-class/derived types in the same container type. Sending each type independently (or several instances of the same type) works fine.
In my example I have a Transaction type that contains an unbound number of Atoms, where Atom is an abstract type. There are 2 derivative of Atom, AtomType1 and AtomType2 which each extend Atom and add an additional sub-element element unique to the specialised type.
(You can assume the namespaces/jax-rpc mapping is correct as when used independently from each other, the derived types bind fine.)
My Types...
| <complexType abstract="true" name="Atom">
| <sequence>
| <element name="atom_id" type="nonNegativeInteger" />
| <element name="name" nillable="true" type="string" />
| </sequence>
| </complexType>
|
| <complexType name="Transaction">
| <sequence>
| <element maxOccurs="unbounded" name="atom" type="myns:Atom" />
| </sequence>
| </complexType>
|
|
| <complexType name="AtomType1">
| <complexContent>
| <extension base="myns:Atom">
| <sequence>
| <element name="atom_type_1_value" type="unsignedLong" />
| </sequence>
| </extension>
| </complexContent>
| </complexType>
|
| <complexType name="AtomType2">
| <complexContent>
| <extension base="myns:Atom">
| <sequence>
| <element name="atom_type_2_value" type="unsignedLong" />
| </sequence>
| </extension>
| </complexContent>
| </complexType>
First example which is processed fine, and proves the type is bound correctly. Single Atom in the Transaction

The next Transaction contains 2 different Atom derived types, and fails processing with this exception

Just for a test, I switched the order of the Atoms in the transaction and note that the binding exception is now accredited to the other derived type

The final Transaction contains 2 atoms of the same derived type - and is processed fine.

Worth raising a bug?
