MQSeries.net :: View topic - Issues with NEON formats and Input Node Convert

We have message flows developed in MQSI 2.0.2 using NEON formats and are experiencing strange behaviour when we turn the Convert option on in the Input node.

In the flows we have compute nodes where we do not change the actual body of the message so we're using OutputRoot = InputRoot to pass the message through the node. This node is then followed by the output node. This works fine and the message is output correctly when input convert is off. When it is turned on the message fails on output with the error "Output format ITS_IC_PF not in database". However ITS_IC_PF is the name of our NEON input format. It appears to me as though MQSI thinks that the message body has changed and expects it to be in an output format? But this does not make any sense as it works fine without the convert option turned on and we have not changed the message body.

I can get around this first problem by forcing the mapping of input to output format in the compute node.

However, there is a second problem. We have a NEONRules node in the flow. If the message fails in this node an error is thrown, caught at the input node and the original message is passed to the output node. Once again this functionality works fine in the message flow without the convert option, but when convert is turned on the message again fails at the output node with whatever parsing error the NEONRules node generated.

We can recreate this behaviour on both NT and Sun Solaris.

Has anyone seen anything like this before? Is there anything obvious that we are missing related to turning on convert on the input node? Any help would be greatly appreciated.

Thanks
