Data mismatch in message mapping in SAP PI

[resham_naaz]

Hello experts

So I have an issue here. I have xml data with structure like that includes :

<email_ids>
<id>12@test.com</id>
</email_ids
<email_ids>
<id>34@test.com</id>
</email_ids>

The occurrence of email_ids is (0,unbounded) so it should be able to occur several times without issue. The mapping is straight as source and target structures are the same. I just use map with default so the blank fields can be populated. Now, the issue is while testing the id field is populated ok once, but all the subsequent times, it either has a mismatch or it is not populated at all. Could someone please tell me why this is happening and how to fix this. 

Thank you
