MQSeries.net :: View topic - Runtime Error when navigating to MQRFH2.pcs.Topic

lium · Posted: Thu May 13, 2010 1:00 pm Post subject:

The message flow I am developing has a compute node to assign MQRFH2 header before it is wired to Publish node to get published. One input MQ message will result in multiple message published. Each published message has MQRFH2 header, the MQRFH2.pcs.Topic is assigned to a constant. But after message is published, only the first message has Topic assigned correctly, all the left has NULL value. Even if I have a trace node right after the compute node and before the publish node, the trace shows the Topic was really blank except the first message.
When I debug through the message flow, Everything seems fine in term that the value assigned to the MQRFH2 header. But after the compute node, when I navigate to MQRFH2.pcs.Command, it is fine with value "Publish", but when I navigate to MQRFH2.pcs.Topic, I got error as:
Computing hasChildren(Time of error xxxxx): An internal error occurred during: "Computing ahsChildren" java.lang.NullPointerException

Retrieving labels(Time of error: xxxxx): An internal error occurred during: "Retrieving labels" java.lang.NullPointerException.

My understanding is: there is runtime error, so even if the compute node has assgin an constant value to the Topic, the Topic is set to NULL after it comes out the compute node. All other fields are ok except the Topic field

Could anyone give me clue?

Great Thanks
