Hi,
I have a flow which processed message from JMS input node from Tibco EMS server and puts the processed message into another JMS queue.
Today we have strange issue.
One of the message is directly coming out of JMS input node into failure terminal and that our error handler is failing. Error handler works fine if message is transformed to MQ using JMS to MQ transform node.
Problem is when message directly goes to failure terminal without transforming.
My piece of ESQL which fails when message comes directly from JMS failure terminal is as below,
It fails when it is executing highlighted statement
DECLARE mqHeader BOOLEAN EXISTS (InputRoot.MQMD[]);
IF mqHeader <> TRUE THEN
SET MSGID = InputRoot.JMSTransport.Transport_Folders.Header_Values.JMSMessageID ;
-------------------------------------------------------------------------------------------------
SET OutputRoot.JMSTransport = NULL;
DECLARE REF1 reference to OutputRoot.Properties ;
CREATE NEXTSIBLING of REF1 DOMAIN 'MQMD' NAME 'MQMD';
SET OutputRoot.MQMD.Version = MQMDE_CURRENT_VERSION;
We are getting below exception when it is trying to create nextsibling,
Any help to figure out this will be appreciated, thanks

Hi eai_guy,
Your previous line of code is not moving REF1 to Properties, it remains at Root and that acts like a document, hence not allowing you to create a sibling.
You should check what structure is arriving at that point, perhaps do a propagate and write to a trace file.
Regards. |

You should always check LASTMOVE after declaring a REFERENCE.
'DECLARE myRef REFERENCE TO myFieldRef' is like a MOVE - it will fail if myRef cannot be associated with myFieldRef. |
