Copy one message into another

 Are you doing the copying the message within a construct message block?

P.S. Once the construct message block finishes, the message is immutable.  You can’t make any changes after the construct block.

 Hello

Thanks for the responses.
Yes I am doing it all inside the same construct block.
In fact here is my real – non obfuscated – code

System.Diagnostics.EventLog.WriteEntry(“1″,”1”);
msgEDIRebateCopy = msgEDIRebate;
System.Diagnostics.EventLog.WriteEntry(“2″,”2”);
msgEDIRebateCopy(Rebate.PropertySchema.CompanyNumber) = 905;
System.Diagnostics.EventLog.WriteEntry(“3″,”3”);
msgEDIRebateCopy(Rebate.PropertySchema.EDIDocumentNumber) = 22;
System.Diagnostics.EventLog.WriteEntry(“4″,”4”);
msgEDIRebateCopy(Rebate.PropertySchema.EDIBatchNumber) = 546;
System.Diagnostics.EventLog.WriteEntry(“5″,”5”);

So what I have done is write out a number to the eventlog at each stage of the operation so that I can tell where it is failing.
It gets as far as the number “2” being written and then it fails.
If I run it through the Orchestration debugger I see that “msgEDIRebate” is a full XML document but even once I have moved passed “2”,”2″ line I see that msgEDIRebateCopy is NULL – it never gets populated.

BTW the construct block is set to construct the msgEDIRebateCopy message.

TIA 

 I fixed it !!!!!! [:D]

First of all thank you to the responses above. I followed the link and determined that I had to copy the CONTEXT as well as the message.
So my new code looks like this:

System.Diagnostics.EventLog.WriteEntry(“1″,”1”);
msgEDIRebateCopy = msgEDIRebate;
msgEDIRebateCopy(*) = msgEDIRebate(*);
System.Diagnostics.EventLog.WriteEntry(“2″,”2”);
msgEDIRebateCopy(Rebate.PropertySchema.CompanyNumber) = 905;
System.Diagnostics.EventLog.WriteEntry(“3″,”3”);
msgEDIRebateCopy(Rebate.PropertySchema.EDIDocumentNumber) = 22;
System.Diagnostics.EventLog.WriteEntry(“4″,”4”);
msgEDIRebateCopy(Rebate.PropertySchema.EDIBatchNumber) = 546;
System.Diagnostics.EventLog.WriteEntry(“5″,”5”);

And voilla it now makes it all the way to number 5.

If you are interested and have time read on:

There are currently 2 projects in the solution. “Claims” and “Rebates”.
The Claims project always existed from before I started here.
When I joined I was asked to create a “rebates” project.
It is identical to the claims in every way except that
1) It would have a different namespace and
2) The schema would have 2 extra fields (RebateType and RebateValue)

I was told to copy the Claims project EXACTLY – only change variable names etc to match rebates.
So I did this. Eg: The message copy code is taken verbatim from claims – it does not have any CONTEXT copying and yet it works fine.

Weird!
