Is it possible to add an attachment in an adapter module

Question

Hi,
I'm trying to add an attachment to the main payload in a SOAP communication channel, like this:
XMLPayload extraInfoAsAttachment = new XMLPayloadImpl(); //com.sap.engine.interfaces.messaging.spi.XMLPayloadImpl
//XMLPayload extraInfoasAttach = msg.createXMLPayload(); //--> when trying with this it will also fail
try{
  String text = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><testing>test</testing>";
  extraInfoAsAttach.setContentType("UTF-8");
  extraInfoAsAttach.setContent(text.getBytes());
  msg.addAttachment(extraInfoAsAttach); //provokes exception
} catch (Exception e){
  audit.addAuditLogEntry (key, AuditLogStatus.ERROR, "Failure when adding the attachment");
  audit.addAuditLogEntry (key, AuditLogStatus.ERROR, e.getMessage()); //--> writes UNDEFINED
  throw new ModuleException (e);
But it will fail in the catch block, with UNDEFINED message.
Ive found the same problem, unresolved, here: NullPointerException - Create New Attachment to Message Payload
Any tips? Thanks a lot.

I have tested following for PI 7.0 and Xi 3.0:
public ModuleData process(ModuleContext moduleContext,
ModuleData inputModuleData)
throws ModuleException {
// create a second attachment for the receiver mail adapter
try {
// get the XI message from the environment
Message msg = (Message)
inputModuleData.getPrincipalData();
// create a new payload
TextPayload attachment = msg.createTextPayload();
// provide attributes and content for the new payload
attachment.setName("Attachment");
attachment.setContentType("text/plain");
attachment.setText("Hello World");
// add the new payload as attachment to the message
msg.addAttachment(attachment);
// provide the XI message for returning
inputModuleData.setPrincipalData(msg);
} catch (Exception e) {
// raise exception, when an error occurred
ModuleException me = new ModuleException(e);
throw me;
// return XI message
return inputModuleData;
