How to deserialize an Aegis XML doc containing a collection?

Hi,

I have this class generated by wsdl2java (comments remove):
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "RunExtensionArgumentsType", propOrder = {
    "extensionArgument"
})
public class RunExtensionArgumentsType
    implements Serializable
{


    @XmlElement(name = "ExtensionArgument")
    protected List<RunExtensionType> extensionArgument;

    public List<RunExtensionType> getExtensionArgument() {
        if (extensionArgument == null) {
            extensionArgument = new ArrayList<RunExtensionType>();
        }
        return this.extensionArgument;
    }

}


I have been serialising it for ages using the following code:
    static {
        aegisContext.initialize();

        TypeMapping tm = aegisContext.getTypeMapping();
        Type aegisType = tm.getType( RunExtensionArgumentsType.class );
        if( aegisType == null )
        {
            // Make a new type and register it for the future.
            log.debug( "Registering type for RunExtensionArgumentsType" );
            TypeCreator tc = tm.getTypeCreator();
            aegisType = tc.createType( RunExtensionArgumentsType.class );

QName qName = new QName( "http://groupgti.com/s-service";,"RunExtensionType");tm.register( RunExtensionArgumentsType.class, qName,aegisType );

        }
    }

public static String extensionArgsToString(RunExtensionArgumentsType extensionArgs )

    {
        try
        {
            StringWriter stringWriter = new StringWriter();

XMLStreamWriter xmlWriter =xmlOutputFactory.createXMLStreamWriter( stringWriter );

AegisWriter<XMLStreamWriter> writer =aegisContext.createXMLStreamWriter();


            TypeMapping tm = aegisContext.getTypeMapping();
            Type aegisType = tm.getType( RunExtensionArgumentsType.class );

writer.write( extensionArgs, aegisType.getSchemaType(),true, xmlWriter, aegisType );


            xmlWriter.close();
            return stringWriter.toString();
        }
        catch( Exception ex )
        {

log.error( ExceptionStringConverter.ExceptionWithCauses( ex) );

            return null;
        }
    }

Now I come to deserialize it using this:

public static RunExtensionArgumentsType extensionArgsFromString(String extensionArgsString )

    {
        try
        {

StringReader stringReader = new StringReader(extensionArgsString );XMLStreamReader xmlReader =xmlInputFactory.createXMLStreamReader( stringReader );

AegisReader<XMLStreamReader> reader =aegisContext.createXMLStreamReader();


            TypeMapping tm = aegisContext.getTypeMapping();
            Type aegisType = tm.getType( RunExtensionArgumentsType.class );
            Object result = reader.read( xmlReader, aegisType );

            xmlReader.close();
            return (RunExtensionArgumentsType)result;
        }
        catch( Exception ex )
        {
            StringBuilder msg = new StringBuilder();

msg.append( "Exception whilst trying to convert \"").append( extensionArgsString ).append( "\" toRunExtensionArgumentsType:\n\t" );log.error( ExceptionStringConverter.ExceptionWithCauses(msg, ex ) );

            return null;
        }
    }

but it hits this exception:
        org.apache.cxf.aegis.DatabindingException:

No write method for property{http://groupgti.com/s-service}extensionArgument in classcom.groupgti.s_service.RunExtensionArgumentsType:No write method for property{http://groupgti.com/s-service}extensionArgument in classcom.groupgti.s_service.RunExtensionArgumentsType:

 com.groupgti.services.service.XmlConversionSupport:extensionArgsFromString @ 
XmlConversionSupport.java:162

com.groupgti.services.XmlConversionsTest:testStringToExtensionArgs @XmlConversionsTest.java:65

Now clearly this class can be deserialized 'cos it's used in by the webservice, so what do I have to do to make it use a get().add() instead ofa set() for collections?


Thanks
