  |   | @XmlType(name="invoker-proxy-bindingType")
  |   | public class InvokerProxyBindingMetaData extends NamedMetaDataWithDescriptions
  |   | {
  |   | ...
  |   |    
  |   |    /** The proxy factory config */
  |   |    // TODO DOM private Element proxyFactoryConfig;
  |   | 

I had unquoted this section in the merged jbossxb project, and that is what produced the errors seen in the JBXB-109 issue. Even if I change this to:

  | @XmlType(name="invoker-proxy-bindingType")
  | public class InvokerProxyBindingMetaData extends NamedMetaDataWithDescriptions
  | {
  |    /** The proxy factory config */
  |    private List<Element> proxyFactoryConfig;
  | ...
  | 
  |    public List<Element> getProxyFactoryConfig()
  |    {
  |       return proxyFactoryConfig;
  |    }
  | 
  |    @XmlAnyElement(lax=true)
  |    public void setProxyFactoryConfig(List<Element> proxyFactoryConfig)
  |    {
  |       this.proxyFactoryConfig = proxyFactoryConfig;
  |    }
  | }
  | 

I'm seeing the same error, which is happening on an xml fragment that does not even have the proxy-factory-config element:
anonymous wrote :

If you or Alexey can look into the JBXB-109 issue it would help.
