Hi All,
My environment is MB v5.0 Fix pack 5,Windows 2000.
I have developed a message flow which publishes the information on a particular topic.This flow contains a subflow which actually does the above task.
My subflow is like
Input-->Compute-->FlowOrder 1st Terminal-->Publication
FlowOrder 2nd Terminal-->Compute-->Output.
The above subflow is getting the data in MRM domain with XML physical format.
Here the problem is after Publication node, i.e. when the control comes to FlowOrder node 2nd terminal the data in the XML message is missing.
For example:
Before Publication node the data looks like:
<A>
<B>
<NameValuePair>
<Name>ABC</Name>
<Value>XYZ</Value>
</NameValuePair>
</B>
</A>
After FlowOrder node 2nd terminal the data looks like:
<A>
<B>
<NameValuePair>
<Name></Name>
<Value></Value>
</NameValuePair>
</B>
</A>
That means the data in the Name and Value elements is missing.Why this is happening i could n't understand.
Actually the above data will be useful in the last Compute node.
Can any one help me in rectifying the above problem.
Thanks in advance.

Hi All,
Yeah, Subscribers are receiving correct data.But data is missing after FlowOrder node 2nd terminal.
I checked it thoroughly.The last compute node throws an user exception if the required data is missing.So here I am getting an user exception.
Please suggest what can I do.

Hi All,
When I have a subscription on the topic on which I am publishing, the data is missing.When I remove the subscription on the topic I am getting the required data without missing.

Do you mean if you don't have any active subscribers for that topic then you are getting data? is that correct? |

Not sure why data is missing if you've active subscribers, but if you want to do any processing after publishing you can do that from a subscriber's queue.
If you want to find why data is missing after publication just try tracing.. |

Hi Sri,
Is the subsribers recieng the correct data which ur publishing? Because the flow order does not process the data thru second terminal if anything goes wrong in the first terminal. Make sure that u've no problem in the first terminal nodes!!!

Have you tried switching round the flow order node (1st = MQOutput; 2nd = Publication). If you use transactions, the order they get MQPUT should not really matter because none of them can be MQGET'd until the flow does a commit.
