Custom disassembler gives me empty message when it shouldn't.

Question

Hi

I'm developing a custom Biztalk disassembler. I fill in the body part with required data and pass it back to biztalk, but biztalk forwards an empty message to the send port. Here's the code:

        public void Disassemble(IPipelineContext pContext, IBaseMessage pInMsg)
        {
            message = pContext.GetMessageFactory().CreateMessage();
            message.AddPart("Body", pContext.GetMessageFactory().CreateMessagePart(), true);

            for (int i = 0; i < pInMsg.Context.CountProperties; i++)
            {
                string Name, Namespace;
                object PropertyValue = pInMsg.Context.ReadAt(i, out Name, out Namespace);

                // If the property has been promoted, respect the settings
                if (pInMsg.Context.IsPromoted(Name, Namespace))
                    message.Context.Promote(Name, Namespace, PropertyValue);
                else
                    message.Context.Write(Name, Namespace, PropertyValue);
            }

            var parser = new CUSCAR_D95B();
            var errors = new List<ApplicationException>();
            var doc = parser.Parse(pInMsg.BodyPart.GetOriginalDataStream(), errors);
            var serializer = new XmlSerializer(typeof(EdiDocument));
            message.BodyPart.Data = new MemoryStream();
            serializer.Serialize(message.BodyPart.Data, doc);
            message.BodyPart.ContentType = "text/xml";
        }

        public IBaseMessage GetNext(IPipelineContext pContext)
        {
            var result = message;
            message = null;
            return result;
        }

Send port is just a folder location. Biztalk writes an empty file to it. Any idea why?
Thanks

Check the stream if it needs to be reset.
