Empty target message in 1 to n transformation

Question

I am using a ccBPM to handle a 1:n message scenario.  I believe I have done everything right:
<li>I have created a message mapping where target message has an occurrence of u201C0..undboundedu201D.  When I test the message mapping it works 100% and produces multiple messages.</li>
<li>I have created an interface mapping where the target interface also has an occurrence of u201C0..unboundedu201D.  I have tested it and it also works 100%.</li>
<li>In my ccBPM I have two container elements, one representing the source message and a second container that has the correct abstract interface and which is marked as a multiline container.</li>
However, if the message is processed in the ccBPM, I can see in the workflow log that the target message is empty in the transformation step.
Can anyone tell me what I could have done wrong or how I can debug it further to tell what the source of the problem is?

Hi Everyone
I found out what the problem was.  When one tests the mapping in the graphical mapping tool, you will notice that SAP automatically puts your message inside two tags: <messages><message1></message1></messages>.  These tags make sense of course, but the problem was that I put my message inside these tags manually before sending it to the transform.  The result was that my message that had already contained the message tags was put inside yet another set of message tags.  That is why my transform did not work.
I hope this will help you solve your problem if you encounter a problem similar to mine.
