Hi,
I try to generate the output root from the Parse statement and send to queue, but I get a blank message in the queue instead of the actual message.
When I debug and see, I can see the complete message with headers. The code for parse the blob data to outputroot is below,
| Code: |
| CREATE LASTCHILD of Environment.BusEventData PARSE(busdataBlob OPTIONS options CCSID nCCSID ENCODING nEncoding); |
What could be the reson for this blank message? |

It could be anything. Why not take a user trace and find out?

You can't write Environment into an MQ message. MQOutput only reads from Root.
You can't create a message tree from a bitstream using CREATE PARSE without indicating which message domain is needed. |

My next line of code is,
| Code: |
| SET OutputRoot = Environment.BusEventData.Root; |
When I debug i can see the output root populated with proper values, but when i took a user trace, I found Environment.BusEventData.Root to be NULL.

Can you point out where in that line of code you're indicating the message domain associated with the OutputRoot message tree?

The whole point of user trace is to show you *why* things happen in your message flow. I suggest that you read the earlier messages to find out why this has happened. |
